138 GEOLOGY OF YELLOWSTONE NATIONAL PARK by Don Barr
Yellowstone National Park is located in the Northwestern part of the State of Wyoming on a high plateau.
The oldest rock in the Park formed some 2 billion years
ago and is composed of igneous and metamorphic rock which in time was vertically uplifted along faults during the formation of the Rocky Mountains. group of rocks in the Park are the Absaroka volcanics.
The second oldest
These were formed by the erup-
tion of a great volume of volcanic material some 50 to 60 million years ago.
The
third and youngest group of rocks was created by the eruption of light colored volcanics during the last 2 million years.
It is referred to as the Yellowstone volcanic
rock. The oldest, the Precambrian rocks, are located at the western end of the Beartooth Plateau.
These rocks were at one time covered by Paleozoic and Mesozoic
sedimentary rocks.
These sedimentary rocks were stripped away by erosion, leaving
the Precambrian rocks exposed for a time.
Later they were covered again - this time
by volcanic rocks leaving only small areas now exposed.
These basement rocks are
composed mostly of gneisses. About 50 to 60 million years ago great volumes of magma erupted along the western edge of the Beartooth Plateau forming the Absaroka Range.
The magmas were of
intermediate type, between black basalt and light colored rhyolite.
Sometimes these
intermediate magmas pour out of a volcano to form lava flows, but more often they are expelled by escaping steam as fragments blown into the air.
The larger fragments
settle around the vent and on the slopes, building up a volcano, while the lighter material drifts off down wind settling into beds of volcanic ash.
The Absaroka is a
complex pile of lava flows interlayered with volcanic fragmental rocks. The Absaroka Range is old enough to be deeply eroded by streams - leaving clean cross-sections through the volcanic pile. lavas.
Some of the lava flows show columular
During the series of volcanic eruptions enough time elapsed to allow forests
to grow and then to be buried by volcanic debris and become fossils.
Erosion has un-
covered many levels or sequences of forest.
Some of the trees are still in the up-
right position.

The rocks from these volcanoes show colors of g r r
The only dark colored rock is obsidian.
The magmas that cooled to
form these light colored rocks were extremely thick and viscous. These thick magmas do not form lava flows, instead the are blown out of the volcanic vent as shreds of molten lava that cool as they settle to the ground. Eruptions such as this are frequently violent.
Some eruptions blow large quantities
of magma high into the air where it cools and settles to the ground as volcanic ash . Other eruptions blow magma out of the volcano so rapidly and in such quantities that they do not cool in the air but settle to the ground to form a we lded tuff.

Surface waters soaking downward into the

The
crusty white material around the geysers and hot springs consists of precipitated minerals. Geysers are a special type of hot spring which operates on the same principle as a coffee pot. Both have a long tube that is being heated at the bottom. The water at the bottom reaches boiling point and would boil if it were not prevented from doing so by the weight of the water in the tube above. the water becomes superheated and expands.
So, instead of boiling,
This forces some water out of the top of
the tube and relieves the superheated water beneath, which immediately flashes into steam.
This blows the whole column of water out of the tube to cause the geyser to
erupt or the coffee pot to perk.
After the geyser erupts it must refill with water
before another eruption can occur. regularly and often.

dissolved in hot water as the water flowed through and around the underground rocks. The water with the dissolved mineral comes to the surf ace and spreads out over the surrounding ground surface where the mineral is precipitated to form solid terraces. In all of the areas of the Park with the exception of Mammoth Hot Springs the material is sinster with the chief constituent being silica.
At Mammoth Hot Springs the
deposits are travertine, which consists mostly of calcium carbonate.
The material
deposited at any given place reflects the kind of rock through which the hot water has passed during its underground travels.
At Mammoth Hot Springs the water passes through
thick beds of limestone which is calcium carbonate, but in other areas the water passes
throughr~ckslike
rhyolite which is rich in silica.
The color of the mineral deposits is generally white to grey.
Around the hot
springs the terraces are commonly colored because of the algae that grows in the pools. These plants grow well in temperatures up to 170 degrees F.
Oxides of iron and
manganese also contribute to the coloring in some of the terraces.
Some of the pools

Mud pots activity dif-
fers from season to season and throughout the year depending on the varying amounts of rain and snow that falls on the surface. Most of the thermal areas are related to the ring of fracture zones of the Yellowstone Caldera.
Many of the deep-seated faults and fractures .in these areas are
presumably situated above the main source of the heat.
The fractures and faults
provide convenient avenues of travel for underground water to circulate to great depths, there to become heated and then to return to the surface.
A few areas such
as Mammoth Hot Springs are located outside of the ring of fractures of the caldera. In these areas the thermal activity is related to other zones of faulting which also afford readymade channels for the circulation of water.

THE WEST SIDE ROAD by John H. Whitmer, M. D. A mile beyond the Nisqually Entrance to Mount Rainier National Park, the visitor passes an inconspicuous road junction marked only by a small sign indicating "West Side Road".
Few people notice it as they drive by.
it, for it is unpaved.
Even fewer are tempted to explore
This road leads to a lovely, yet stupendous, aspect of Mount
Rainier, exposing geologic features which reveal much about the nature of the great volcano. The road follows the valley of Tahoma Creek to Round Pass, at 3900 feet elevation, then descends across the South Fork of the Puyallup River, proceeding past Klapatche Point to the North Fork of the Puyallup River, in the course of about 15 miles.
These three streams are fed by large glaciers, and their valleys have carried
at least nine major mud flows in the past 3600 years.
The largest of these lahars,
the Electron Mudflow, occurred about 600 years ago, sweeping 30 miles down the valley of the Puyallup River, almost to the site of the City of Sumner (Crandell, 1971). flows have occurred in our era, too.
Mud-
In 1967, and again in 1970, lahars inundated the
Tahoma Creek Campground, 3 miles downstream from the Tahoma Glacier.
The campground
was promptly downgraded to a picnic ground for the sake of public safety. Initially, the road is in rain forest, with views of the swampy flood plain of Tahoma Creek to the right.
At 3.2 miles it crosses Dry Creek, notable for the frequent
debris flows which it carries, debauching them on Tahoma Creek's floodplain, killing trees and disrupting drainage.
Beyond Dry Creek, to the left, Mount Wow abruptly rises
3500 feet, with cliffs which are sheathed with ice in the winter.

mountainous terrain on which Mount Rainier was built, Mount Wow consists of a lava complex of the late Eocene Ohanepecosh Formation. Ground.
At 4.3 miles is Tahoma Creek Picnic
This is the roadhead for the Tahoma Creek Trail, which leads to the Wonder-
land Trail and a wonderland of wildflowers (as many as 63 different kinds of blossoms on one hike), lahars, glacial moraines, the Tahoma Glacier and the South Tahoma Glacier.
The South Tahoma Glacier was apparently the source of the mudflows which
aggraded the Tahoma Creek Picnic Ground.

Mount Rainier.
The Tahoma Glacier dominates the scene, descending from the summit
cone of Mount Rainier (Columbia Crest) through a breach in the wall of the primordial summit crater (in which Columbia Crest was built) and disappearing below tree-line in the valleys of Tahoma Creek and South Fork of Puyallup River.
The breach is the
reason for the many mudflows in these valleys, for it conducted meltwater and debris from the eruptions which built the summit cone, in the manner of a giant sluice.
At
Round Pass, road cuts expose the Round Pass Mudflow, 2800 years old and as much as 25 feet thick and seven miles long. From Round Pass, the road descends 1.4 miles to the South Fork of the Puyallup River, which originates from one of the snouts of the Tahoma Glacier. Trail follows the stream up to the Wonderland Trail, elevation gain.

The South Fork

Everyone should make this hike, for it leads through rain forest
carpeted with Canadian Dogwood, to a magnificent cliff of columnar andesite rising from the forest at the Wonderland Trail Junction.
With its accumulation of fallen
columns a foot and a half or more in diameter and 10 or 15 feet long, it dwarfs the Devil's Post Pile.
Softly illuminated by light filtered through the forest, it is a
paradox of exquisite beauty and stupendous size.
It silently tells us that Emerald
Ridge, between the South Fork of the Puyallup River and Tahoma Creek, is an intracanyon flow.
The graceful curves of the columns at their bases gives clues to the
contour of the old valley floor.
The modern streams were cut into the old ridges
that contained the lava flow, which is of Pleistocene age.
From the junction, the
Wonderland Trail leads steeply upward, abandoning the valley to cross moraines, cirques, and meadows on the surface of the lava flow for 2 miles, until it reaches the prowlike apex of Emerald Ridge, surmounted by green grass and alpine flowers, and undergirded by solid rock which splits the Tahoma Glacier into a lobe which descends Tahoma Creek Valley, and a lobe which plunges into the canyon of the South Fork of the Puyallup River.
It is hard to imagine a more wonderful place, for here you can
look up to the top of Tahoma Glacier at the crest of the volcano

and down to the
snout of the Puyallup River lobe, with ponds of water trapped in its crevasses, and streams noisily issuing from the ice.

North of Tahoma Glacier is the massive Klapatche Ridge,
an andesite flow, which narrows upslope into the Puyallup Cleaver, a dike
which separates the Tahoma from the Puyallup Glacier.
The dike penetrates Klapatache
Ridge, Where Tokaloo Rock, its most salient portion, juts out of the ridge like a huge, triangular wall.
In the upper South Fork Puyallup River Canyon, the so lid
andesite of Klapatche Ridge is being undermined where it rests upon unconsolidated material which must have constituted the floor of the canyon into which the Klapatche Ridge lava flowed. A more strenuous hike begins at the trail junction of the Wonderland and the South Fork Trails.
The Wonderland Trail north from there leads across the river and
onto the Klapatche Ridge, where it climbs steeply.
One can leave the trail near its
highest point and climb Klapatche Ridge to Tokaloo Rock, the Cleacer, and the glacier s . It is very hard work, but the views are great! Upon leaving the South Fork Puyallup River Trail via the West Side Road, one soon encounters road cuts in massive mudf low.

it is coarse lahar, about 15 feet thick, and overlain by bomb-bearing block and ash flow deposit (Crandell, 1971).
Its age is estimated at 2500 years by radiocarbon

(2~
miles; about 1700 feet elevation gain) and Klapatche Park, a
lovely spot which affords fine views of the mountain, and where Gentians abound. Klapatche Point, at 12.3 miles on the road, is worth a stop, for two fine dikes crop out below the road, but cannot be seen from the car. cut valley of the Puyallup River lies below.

Here, the contrast between National Park
and private land is stark, for on the other side is a big logging operation which has denuded an exceedingly steep slope, leading to gullying and debris flows which reach the river. Upon rounding Klapatche Point, the road descends along the wall of the valley of the North Fork of the Puyallup River.
It reaches the river but does not cross it.
The ruins of bridge abutments show that the original plan was to continue the road

The road ends at a truly
spectacular place, for about 3000 feet above it a tongue of the Puyallup Glacier hangs vertically in a couloir, appearing ready to crash down into the valley at any moment.
The swift stream tumbles and roars, fed by that lobe and a second one a half
mile to the north.
Partly concealed by a huge rock, that lobe is easily overlooked,

Then it was Shanks Mare

On
my right was a bluff ranging from 3 feet to 60 feet
This is the Gresham Formation melding into the Estacada Formation.
Graphic evidence of the recent wind storm lay scattered throughout the woods, and along the road.
Below a thick rock bulkhead the bluff became more prominent.
The nearer the road came to the Sandy River, the thicker became the mudflow, cobb le gravel and bouldery gravel.
The outer surface of the formation exhibited heavy
weathering, and occasionally brief faults appeared.
As I continued my walk three
small waterfalls were apparent, the largest having a fall of some 12 t o 22 feet, dropping into a small basin, then flowing under Stark Street.
Below the falls the
gravelly strata showed more plainly, interspersed with mud flows. Nearing the Sandy River the bluff on my right made an abrupt turn to the east. At this point it was some 12 to 30 feet in height.
The Stark Street bridge, which
crosses the Sandy River, terminates at the Crown Point Highway.
A Plaque on the
bridge girder informs one and all that the bridge was built in 1914 by the Oregon State Highway Commission, Henry Bowlby State Highway Eng. I walked a half mile west on Crown Point Highway, and the same distance to the east.
In the mile that I checked, the bluff on the north side of the highway
averaged some 80 feet in hight.
It is is a veritable cornucopia of mudflows inter-
spersing breccia-like gravel strata. saturated.

The largest boulders averaged 8 to 10
inches in diameter , many were clearly basaltic.
The base of the bluff seemed to be
sandstone, while what appeared to be ripple marks showed in two places. Walking back to Mount Hood College I stopped at the largest of the three waterfalls.
As I checked the fall of water a bit of gravel popped into the air, falling
into the pool at the bottom. Erosion actually happening. It struck me that the water was doing its job, peneplaning the land. At Kerslake Road I walked some half mile, reaching a small creek running under a tangle of blackberries. fed the largest waterfall.

side, sliding and slipping along its meander from the Kerslake Culvert Road to the waterfall.
The area still had several trees retaining their fall colors.
The little
pool fronting the culvert was filling with leaves decaying into the silt, while at its edge a thoroughly beat-up T.V. cabinet sagged creekward.
Occasionally I could see a
pebble rolling along the bed of the creek as it continued to cut into the breccia-like gravel strata that were exposed in a couple of places.
Walking back up the creek,
heading back to the college, I shivered once or twice, but that's ridiculous, the ice melted ten millenia ago, right?
Miles walked - 9.4 .
Gresham Formation Gravel and mudflow deposits in terraces along the Sandy River and correlative gravelly deposits in terraces along the Clackamas River represent alluviation of valley cut into Springwater Formation.
They are of probably Middle Pleistocene age
and are here named the Gresham Formation.
This formation is present on both sides of
the Sandy River and extends to the eastern edge of the mapped area to within about a mile of the town of Troutdale.
Deposits assigned to this unit underlie the town of
Gresham, from which the name is taken. Cobble gravel and bouldery gravel compose most of the Gresham Formation, but, as in the Springwater Formation, mudflow rocks are important constituents along the Sandy River.
The mudflow deposits range in thickness from 10 feet to about 50 feet. The age assignment of the Gresham Formation is also relative.
Based mainly on
the relative topographic position and degree of weathering, the · Gresham is considered to be of Middle Pleistocene age. Estacada Formation Still another group of
all~vial
gravel and small mudflow deposits of probably
Late Pleistocene age, occur along the Sandy and Clackamas Rivers.
They are named the
Estacada Formation for the town of Estacada which is in part sited on these deposits. Locally, along the Sandy River, the Estacada Formation is as much as 100 feet thick.
Like the older alluvial deposits, the Estacada consists mainly of cobble and
bouldery cobble gravel.
The gravel along the lower Sandy River for about 11 miles up-
stream from the town of Troutdale, however, is commonly overlain by a persistent stratum of evenly bedded sand that, locally, is between 50 and 100 feet thick. As in the older alluvial deposits, the materials composing the Estacada

The Agate and Mineral Society Gem Show, held at OMSI the last four days in February, lived up to its reputation for beauty and fascination. GSOC members who displayed were:LIDIJA BALODIS, with a forest of gem trees in one case, and rough and polished amber specimens and amber jewelry an a second case. BILL and ESTHER KENNEDY had a wide variety of zeolite specimens, mostly from Oregon. LEW and MURA BIRDSALL joined forces with Cloyce Joerg to put in a display of gem stones, rock, and shell from Australia and New Zealand. AL and RUTH KEEN showed a case of petrified wood , some slices, but mostly cubes. Some of us haa the privilege of seeing those cubes at a luncheon recently. RUTH KEEN, always the teacher, displayed two 8-foot cases filled with 120 crystal shapes cut of wood, many accompanied by crystal specimens. CYNTHIA and LEO SIMON had a case that would have delighted the heart of any collector. It was an 8-foot case filled with fabulous carved pieces - ivory, soapstone, amber, jade, coral, turquoise, and others. MAE KJOS jaunted up to Olympia recently to visit her daughter and to help her grandson celebrate his 10th birthday. Sorry to say that LLOYD WILCOX has had another sizable stay in the hospital.

APRIL 1982 AND THE MULTITUDES GATHERED 'by Peigi Stahl
One hundred and forty-four of the faithful joined together at Smith Memorial Center, Portland State University, on the evening of March 12th to partake of supper and see a new President and Board of Directors installed.
The evening was one of
gaiety, with music and singing, and enriched by a paleontological address.
Hopefully
Dr. Orr, who takes his fossils seriously, wasn't too shaken by our somewhat off-key rendition of "Land of the Fossil Hunters". The 47th Annual Banquet proceedings began at 5:30 P.M. with the sales tables going into action and the exhibits arranged for all to see and admire. Dinner, served at 6:30, consisted of Agate Melange, Herbed Archeopteryx with Obsidian-splinter Dressing, Steamed ·calamite Stems, Hot Volcanic Bombs and Sulphur Chips, Baked Pegmatite Dikes, and a choice of Limonite, Chlorite or Chalk in Solution to drink. Promptly at 7:30, and Joe is known to be prompt, outgoing President Joseph Beemer rose to welcome the assemblage.
Dr. Arthur Jones presented the Invocation,
and Master of Ceremonies Wally Mcclung introduced the officers and guests and then went through a bit of hi-jinks in which we found, as usual, that Theodore and Florence Johnston had travelled the farthest to attend the banquet and that Leo Simon belonged to more organizations than anyone else present. At the swearing-in ceremony everyone being installed into off ice for the coming year looked in top form except our secretary, Eleanor Pankow, who is starting her second term in office with a broken arm.
Guess who went skiing?
The honor of Fellowship was awarded to Effie Hall and Esther Kennedy for their past efforts in behalf of the Society. Joe Beemer was made a Fellow of the Society for his service as President for the past year.
He then gave his farewell address.
( I have always wondered why it
is called a "farewell" address when the outgoing president is expected to remain present to help run the Society for the following two years.) Joe thanked all participants who helped to make his year as president a success, then handed over the book, the gavel, and the pick to incoming President Ruth Keen, who, he suggested, could be expected to do some fiddling around.

Both
addresses and the invocation may be read elsewhere in this issue of the Newsletter. Intermission gave us a chance to move around a bit and then we settled down again to hear an address on Oregon Paleontology by Dr. William N. Orr.
Dr. Orr is a
Professor of Paleontology at the University of Oregon, and the author, with his wife Elizabeth, of the recently published Handbook of Oregon Plant and Animal Fossils. Geesockers drooled over his slides of plant and animal fossil~, and were much interested in seeing pictures of earlier paleontologists we have long heard about and whose works we have read. The evening ended on a musical note, the music being provided by the GSOC Pops, a group which included Ruth Keen with her fiddle, Charlene Holzwarth, drums, Al Keen and Wally Mcclung, guitar, and Marija Janko and Margaret Steere, recorder. played several numbers, Wally even sang a bit.

Annual Banquet
March 12, 1982
Let us all pause for a few moments of meditation as we gather together here. May we be ever mindful of those many comrades who have helped to form this fellowship which we all share, and be grateful for their interest, imagination and vision which have made possible this very gathering: - such as Edwin Hodge, Al Vance, Lon Hancock and Berrie, Jack Stevens, and so many others . May we be thankful for the privilege of living in this great Oregon Country , for the widening of our concepts of the eons of time, the vastness of our universe and the untold variety of life forms which the strata of our beloved hills and shores have made manifest to our exploring picks and minds.
Let us give thanks for the joy s
in sharing the thrills of discovery of new proofs of how this marvelous world has grown, changed and flowered, enriching the lives of each of us here. We would share this moment of thanks for the food that is set before us, and for "fossils and agates, and geodes galore, - and nodules all over the ground!"
Amen.

At that time I was told by the
Nominating Committee that I should understand that I would not become President as they would not have a woman for President. Times have changed.
I am your second woman President .
Opal Helfrich preceded
me in 1976 with a fine year. "You lucky people!"
A friend of mine who used to lead climbs on the North
Sister always called out "You lucky people!" when we were in our most precarious situations . We are not in such a situation now, looking foreward to a new GSOC year, but we are indeed lucky to belong to this group of people, all dedicated to the enjoyment of the geology of the Oregon Country as well as to that of other reigons and to adding to our knowledge and understanding of geology.
We are also dedicated to fellowship
with each other. We are lucky to have such a fine Board, just introduced, to carry out the business of our Society, and the following Committee Chairmen: - Banquet Chairman, Esther Kennedy; Calligrapher, William Freer; Trips, R.E. (Andy) Corcoran; Richmond;

Dates are
Bend has the accommodations that we will need .
that most of our trips can be made by bus.
I hope
More later.
We will need the cooperation and help of all of you to make 1982 a successful and memorable year.
Thank you .

TRIVIA by Peigi Stahl Once, on a GSOC fossil hunting trip, our learned leader, who was very well versed in paleontology, pounced excitedly on a bit of something that he explained was an earbone of a rare and extinct species.
To me it looked like a beautiful specimen
of Leaverite (leave it right where you found it) and I did. However, if you are the kind of person who gets excited over extinct earbones you should know something about barnacles. lots of excitement should you ever find any.
Fossil juvenile barnacles could give you It helps if you know what you are
looking for. From the book "Sea Beach at Ebb-Tide", by Mr. Augusta Foote Arnold, I have gleaned some interesting facts.
First, anyone who ever gets to the beach can recog-
nize an adult barnacle, and fossil barnacles look much the same . arthropods, Arthropoda meaning joint footed. curled feet.
Barnacles have feet?
Barnacles are
Their Order is Cirripedia, which means
Well, yes, they do, but it has to be explained
from the beginning. The young barnacle, called a nauplius, emerges from the egg as a free and independent animal, with one eye, three pairs of legs and a single shell.
After it
swims about for a while and moults several times it has two eyes, six pairs of legs, two shells and a desire to settle down. It pickes out a spot, attaches its anterior end (that's its head) by means of its antennae, which have transformed into suckers, and secretes a cement which permanently fastens it in its chosen location. Now it makes further changes.
It loses its bivalve shell and its eyes and de-
velopes its characteristic cirripeds or curled feathery legs and a new shell covering. During the last changes, since it has become attached, it doesn't eat, living by the absorbtion of its own body fat. After the cirripeds are developed the barnacle uses them to gather in the minute animal forms that float past it in the sea water. ting parts of its outer covering.
Further growth is by moul-
The shell is permanent.
You now have a recognizable adult barnacle, but should you come upon a tiny sea creature with one eye, three pairs of legs and a single shell, you have every right to get excited.

TRIVIA by Peigi Stahl Here I am with a half page and nothing to fit it so I thought that since we are going off on Margaret Steere's field trip looking for invertebrate fossils I could tell you a little about the invertebrates we might be finding. I am ta.k ing my information from the book "Life on Earth" by David Attenborough. his TV:w•r·tes based on the book was shown on channel 10 and will no doubt be repeated next year. If any of you missed it it wasn't Viola Oberson's fault. She enthusiastically encouraged everyone to see it. 3,000 million years ago there was already life in the ocean. Between 1,000 and 600 million years ago the first marine invertebrates began to evolve. A place had been prepared for what was to come. The erosion of the continents produced sand and mud on the sea floor around their margins, and much organic material fell to the bottom from the waters above. Flatworms evolved very early in the game, but it is hard for them to burrow. With all this good stuff laying around it was only natural that something come along to take advantage of it and the round worm developed to do just that. They diversified and some lived in a protective tube. In time the top of this tube was shaped into a collar with slits in it. Taking the minerals from the sea and modifying still further, the worm was eventually housed in two flat protective shells. This was the first of the brachiopods. Where there is no change in the environment there is little or no change in the species, but as time passed and in places the conditions changed the species living . there changed slightly to take advantage of the new conditions. Several species of brachiopods developed a hole at the hinge end of one of the valves through which the animal sent a worm-like stalk to fasten itself to the bottom. While this was going on another worm continued to crawl around on· the bottom and secreted a small cone shaped tent of shell under which it could huddle when danger threatened. This was the ancestor of todays mollusks. Among the mollusks diversification was practically their middle name and today there are about 60,000 different species. The internal organs of the mollusk are housed in a thin shee.t of tissue called the mantle. The upper surface of the mantle secretes the sh~ll~ continued on page 179.

174 METAMORPHISM by Geneva Ressel
Evidence suggests that the eastern margin of the Pacific Ocean Plate is being shoved under the continent of North America. historical geology in the Oregon Country. at the rate of 2.6 centimeters per year.
This shoving motion has affected
At the present time the movement continues Compression tectonics forms faults, broad
folds, and imbricate thrusts and is the environment for metamorphism of rocks and .'
sediments as the continent rises and subsides.
Let us take a look at that environ-
ment. · Metamorphic rocks are those which have been modified in a solid state in response to change in the physical or chemical environment below the zone of weathering or cementation. of a melt phase.
All processes take place in a solid rock without the intervention
Solutions make up a small fraction of the volume of the reacting
mass. During metamorphism the bulk composition of the rock may remain essentially unchanged or it may be drastically changed.
Texture and , relationships among grains
are controlled by the ability of different minerals to make room for themselves.
The
materials needed for growth of crystals must be transferred through solid rock or along intergranular boundaries to the site of the growing crystal. metamorph~c

The sediments themselves
Some types of sediments remove

Considered to be a minor source of heating is friction during faulting or thrust faulting because the zones of fracture have access to the surface or circulating water. Finally, heat from within the mantle or convection overturn does nat seem adequate to account for the great regionally metamorphosed areas . Hydrostatic pressure within the earth is that of ground water and is generally

due to the weight of water at higher levels in the same zone of saturation. Lithostatic pressure is equal, all-sided pressure due to the weight of overlying rocks.
Fluid pressure is the result of fluid present in the rock, or fluid present
in connected channelways to the surface or to shallower depths within the crust.
Di-
rected pressure or compression may be relieved by faulting or by recrystallization and is therefore the less significant pressure. In closed-system reactions there must be a gain or loss of material and most reactions are reversible if the evolved gas cannot escape.

reached quietly and the reaction will not proceed. In open-system metamorphism the bulk composition is changed appreciably by the introduction and/or removal of constituents.

Commonly termed Metasomatism the agents
are most often fluids or. gases migrating through fractures or along intergranular boundaries.
Some metasomatic processes have been explained by migration of ions over
some distance through rocks.
Undoubtedly, the main components of the fluid phase are
water and carbon dioxide, but because of the high temperatures and pressures involved L
and the nature of the channelways, the water and carbon dioxide must behave differently than solutions found in surface water.

temperature and
pressure ranges must be a dense gas and pass along the channelways at a thickness of one molecule.
Diffusion of activated ions must be rapid and must involve different
ions moving in the opposite directions.
In metasedimentary rocks, the source of
fluids was deposited with the sediments or migrated from adjacent sediments. waters contribute sodium.
Salt
In addition, progressive dehydration of rock is through
the formation of less hydrous or anhydrous minerals.
A final and perhaps most impor-
tant source is de-gassing of the upper mantle and lower crust.
If these very hot
gases were not involved in magmatic activity they would have to escape upward by permeation through the rocks, developing mineral phases that would be stable in that particular chemical and physical environment. The gases would probably be siliceous and alkaline so that the mineral phases developed would be minerals of the granite family.
These processes are required for regional metamorphism.

Membership Chairman, Ruth Goldson reported 89 visitors at the evening lecture meetings and 26 new memberships to the Society. Chairman Bob Richmond reported on the Volunteer Speakers Bureau. This serviee was initiated early in 1980 to provide volunteer speakers from our Society specifically to relieve demand on the Portland State University F.a.rth Sciences Department for informal talks on ~t. st. Helens and Vulcanism in general. From April 1980 through February 1981 three volunteer GSOC members Norm Hess~l, Clair· Stahl and Don Turner filled 36 speaking engagements in the Portland metropolitan area.
Dr. Michael Cummings, Assistant Professor of Geology, was introduced by President Joseph Beemer, He thanked the Geological Society of the Oregon Country for past scholarship gifts.

Their basic need is tuition for scholarship support. President Joseph :Beemer had the secretary read Article II, section 3 of the Bylaws and then an amended version of Articie II, section 3: A Fellow is a member who has made significant contributions to the objecttives and welfare of the Society. All past presidents who are members in good standing, in view of their services to the Society, are to be awarded Fellowship at the completion of their tenns of office. Election of any other members to fellowship status must be by unanimous vote of the Board ot Directors. Be entertained a motion to ratify this revision. Motion was made, seconded and __ membership voted un8.nimously in favor. This means a president in good standing will be awarded Fellowship status at the completion of his tenn of office.

Many mollusks have a single shell. Limpets, the cap shaped mollusks, produce shell at an equal rate around the circumference of the mantle and create a tent-like housing. The chambered nautilus' mantle secretes faster at the front than the rear and the llhell developes in a flat spiral. When the maximum production comes from the ·side the •hell twi•ts and becomes a turret, like the conch and murex shells. The cowerie concentrates its secretion along the sides of the mantle producing a shell like a loosely clenched fist. Dr. Attenborough does not tell us how the bivalves like mussels and clams form their· shells and far be it from me to offer my humble opinions on the subject (at least not in print). These are the type of fossil shells you can expect to find on the upcoming field trip. There are species that have lost their shell, like the octopus and the squid, but these do not fossilize well so don't look for any. Hope this makes your fossil hunting more interesting.

For this they needed docks to load the
The McCormicks also needed ships to haul the lumber, and so they built up a
steamship line of some 30 ocean going vessels.
Their ships sailed the seven seas.
Hence, the sawmill family became a steamboat family, and thus, the McCormick Steamship Line was formed. However, our story is not about sawmills and steamships; it is about a landslide at McCormick Pier.

They finished it by January, 1982.
In so doing, FSI used the techniques of both engineering geology and civil engineering (soil mechanics) to explore the weaknesses of the McCormick Pier soils and recommend the treatment needed to strengthen these soils so they could support the apartment buildings in an entirely satisfactory manner. GEOLOGY When the pioneers arrived in Stumptown (as Portland was then called) the area was underlain by two Pleistocene alluvial formations left there by the Willamette River at older stages in its long history.
The oldest formation, which underlies
the entire area, is a well-bedded flood plane and channel deposit made up of a compact silt, sand, and gravel.
It contains carbonized leaf fossils.
Above it, the
other formation is a loose sand and silt deposit that occupies an ancient channel carved into the bank of the river.
This channel was cut by the rushing waters of the
Spokane flood. Above these formations is a flood plane deposit that lies below the pavement of much of downtown Portland.
This depo s it is from Recent to Late Pleistocene in age.

The other was built on Douglas Fir piles driven into the river bank, and,
beyond the bank, into the river itself. Sometime . after 1958 this riverside warehouse was torn down but the piles were left standing.
In order to make the property more attractive to an investor, the
low area of the old warehouse was filled in with cobble and pebble gravel from the Troutdale Formation.
The riverbank was then lined with a riprap of basalt blocks
quarried from the Boring Formation.
Its purpose was to protect the bank from erosion.
THE LANDSLIDE Unfortunately, at a finished s lope of l.3H tolV (ed. 1.3 feet horizontal to 1 foot vertical, or a 39 degree slope) the load of the gravel and riprap was too heavy for the underlying soils to support.
Consequently, part of the bank gave way

Incidentally, the High Water came last March. CONCLUSIONS In summary, the investion concluded that: 1)
The landslide was a planar slump with a ten year history of motion.
2)
The sliding was triggered by the weight of gravels placed along the riverbank.
3)The threat of sliding was eliminated by unloading the top and flattening all the riverward slopes.

He was 88 years of
He is survived by his son, Edwin, of Wilsonville, Oregon, his dau ghter, Clara
Smith, who lives in British Col umbia, n inteen grandchildr en , and sixteen great grandchildren. Murray and his wife Agnes joined t he Geological Society in March, 1952, and actively participated in its functions until her death July 1, 1975.
In reco gn i-
tion of their service to the Society they were granted a Life Membership Mar ch 1, 1967. Since his retirement from the Forest Service in 1959, Murray devoted much of his time to youth programs.
Best known, perhaps, are his contributions to the Camp
Hancock program, sponsored by OMSI; the Outdoor Schools program, sponsored by the Portland Public Schools; and Camp Molalla, sponsored by the Campfire Girls . His interest in the sand dunes along the Oregon Coast kept him busy for years in observing, measuring, and recording their movement s. Perhaps his greatest achievment in the field of conservation was his recognition of the novelty and importance of the Camassia Natural Wildlife Area in West Linn, and his unceasing effort to preserve its unique features from the ravages of urban development.
His efforts culminated i n its preservation by purchase by Nature
Conservancy, the first of seven such natural areas now under the protection of that agency in Oregon. Who that knew Murray can ever forget the Banquet of 1967, when he entertained us with his renditions of popular tunes on his xylophone of musical r ocks, accompanied by the guitars of Paul Howell and Truman Murphy?

189 BOOK REVIEW RED ROCK COUNTRY review by Charlene M. Holzwarth
The author, Donald L. Baars, industrial geologist and teacher, has included many aerial photographs as well as close-ups, isopach maps and fence diagrams.
This
interesting book is divided into three parts with the Early History describing Mesozoic and Paleozoic rocks in Grand Canyon and Canyonlands, Monument Valley, the Natural Bridges of White Canyon, San Juan Mountains (The American Alps), and Zion Canyon. The second part discusses the changes during the Triassic Time and Lower Jurassic Time when its
deserts were comparable to the present-day Sahara.
Weather
conditions enhanced the preservation of dinosaur tracks near Moab, Utah and many bones in Morrison Formation near Vernal, Utah.
The Cretaceous Period found relatively flat
lowlands, with occasional fresh water microfossils, followed by a returning sea in Late Cretaceous.
The encircling volcanic activity in the early half of the Tretiary
Period suggests the only escape route as being nortward across Unita country. The chapte,.. on Pliestocene Time discusses how a river can carve its path directly into the very '
crest of a major uplifted area and come out the victor.
The mysterious and contra-
dictorily locat ed gas fields in the bottom, in areas of low structural position of the San Juan Basin, was described.
A strange phenomenon called "Voodoo Entrada" in
the Valley of the Goblins, weathers into giant multiple fins in Salt Valley in the heart of Arches National Park and is surrounded by areas where the same formation spalls off into rounded, overhanging natural Gothic arches.
The colorful petrified
logs in the Chinle Formation of the Petrified Forest National Park shows the original woody tissues preserved as organic materials completely infilled and enclosed in hard silica.
Cyclotherms are described and possible causes developed.
Searches for oil and uranium continue in Part Three.
Whether you have seen
this spectacular country or not you will enjoy the book, purchased by Cynthia Simon in memory of Johanna Simon.

A TRIP TO ENGLAND by Braden Pillow Louise and I took a trip to England last October that was a real dream.
Friends
from Houston, Texas who used to live in England had taken a cottage in the midlands and invited us to spend two weeks with them.
Accordingly, we flew to London, took
Britrail toWolverhampton where our friends met us and took us by rental car to their cottage in Cockshutford.
This town consists of three houses, but is not far from
Ditton Priors which has twelve houses, a store, church, and filling station.
All
this is in Shropshire, in the heart of the midlands, close to the historic towns of Ludlow and Bridgenorth. With the rental car we traveled all over that part of the country and were able to see a lot in the time involved. ~f

JULY 1982 TRIVIA by Peigi Stahl The current issue of the Planetary Report, a publication of the Planetary Society, has an article that should be of interest to our Newsletter readers.
I wish
I could simply reprint it but it is copyrighted so I will have to give you the gist of i t as best I can.
The title is "Volcanism in the Solar System", by Michael H. Carr,
who is employed by the u.s.G . S. We, in the Pacific Northwest, should certainly know about volcanos.
We are
well equipped with volcanic rocks, have several slightly restless, dormant volcanos, and a real, live-in active one.
Besides that we have television that brings the
activities and results of eruptions from all over the world right into our living rooms.
The Planetary Report article deals with the efforts of planetary volcan-
ologists to understand volcanic processes on other worlds. First comes a good look at Earth's volcanic activity. controlled by
plate tectonics.
Much of this is
Mid-ocean ridges erupt, enlarging the oceanic plates
and pushing them towards the continents.
These eruptions are usually underwater and
only on occasion do they reach above the ocean, as they do in Icland. meet, one usually dips under the other.
Where plates
Along our coast the continental plate, being
lighter, overrides the oceanic plate which is then heated and partially melted. hot magma works its way to the surface and forms volcanos.
The
These magmas are quite
viscous and tend to create a more explosive type of volcano.
Typically they are

Not all volcanos are caused by subduction.
Some, like the
Hawaiian shield volcanos come from "hot s pot s " in the earths mantle. So far they have found no evidence of plate tectonics on other planets, although there may be on Venus . yet know what causes it.
There are signs of volcanism on Venus but they don't
With the exploration of the solar system, scientists are
coming to believe that the types of volcanos on Earth are but a small fraction of the types they may find elsewhere. "-
Between 3 and 4 billion years ago our moon had huge floods of erupted basalt that were very fluid and fast flowing and formed the lunar maria or seas.
The only
eruptions on Earth which can compare in volume are our Columbia River basalts and the Deccan basalts of India. Mars, too, has extensive lava plains, probably created in the same way as those on the moon, but its shield volcanos are its most spectacular volcanic features. They resemble our shield volcanos like those in Hawaii but they are 10 to 100 times J

larger, possibly because the rate of eruption was higher. because of the lack of plate tectonics.
Also they can grow larger
Hawaiian volcanos form over hot spots but as
the plate moves it carries the volcano away and the volcano becomes dormant while a new one forms over the hot spot.
On Mars, the volcano remains in place and grows as
long as magma can be pumped to the surface, maybe for as long as a billion years. Besides the lava plains and huge shield volcanos Mars has smaller cones and thick layers of volcanic ash. Volcanic eruptions on terrestrial planets are almost entirely silica-rich, driven by the heat left over from the formation of the planets and by the decay of radio-active elements.
On the moon and on Mercury volcanic activity ceased early
because they were small and cooled rapidly.
Farther out in the solar system volcanism
differs in both the materials involved and the driving forces. Jupiter's satellite Io is the most volcanically active body found so far in the solar system.
Its surface color, temperature, and the presence of sulfur near
it indicate that sulphur is the erupted material. on earth.
We have had rare sulphur eruptions
Sulphur depos its, which had previously formed by condensation from volcanir
gases , have been melted into sulphur flows.
Io's intense volcanic activity is caused
by the alternate pull and release by the gravity of Jupiter and its satellites. These forces continually flex Io's surface, heating it and driving the volcanism. Different from Io, Europa, another Jupiter satellite, has indications that its surface is continually reworked by tectonic and vo l canic processes.
Its density
suggests that it is largely silicate covered with an ice-rich layer tens of kilometers thick.
There are no volcanos or flows on Europa , only ridges of ice sug-
gesting recent eruptions of water or slush followed by rapid freezing, concentrated along fractures .
This form of volcanism is not found on Earth although a similar
process may occur in pack ice. Jupiter's satellite Ganymede may have had some volcan ism over 3 billion years ago, probably ice eruptions, while Callisto shows no evidence of volcanism at all. Because Saturn's satellites are small no volcanism was expected, so scientists were surprised to find evidence of resurfacing on several.
On Enceladus some regions
are very sparsely cratered, indicating that material probably erupted onto its surface within the last billion years.
The erupted material was probably not water

198 MY MEMORIES OF MURRAY by Laurette W. Kenney
Some men accomplish with fanfare and heraldry. unobtrusively and little noticed.
Other men accomplish quietly,
Murray Miller was one of the latter.
He moved
quietly and alone, collecting and filing infinite data to solidify a theory or discover anew.
It was not until after he had walked the sagebrush-lined path tiown
the canyon, and disappeared behind a bluff, did one fully realize the impact he had made upon the world of science and those around him . I was to meet Murray for the first time at Camp Hancock in the late 1950s.
At
t he time he was a volunteer teaching botany the full three sessions of the camp each year.
Camp Hancock then was in its infancy.

It was for it a period of pri mitive Murray's tent was always on the out-
s k irt s of the camp -- a place to retire to his studies after he had perforoed his pa rticular stint for the camp.
At the time there were new fossil finds around the
c amp attracting nationwide interest.
Lon Hancock was working the Clarno mammalian
beds with the assistance of two students under the pay of the University of Oregon . My husband and I, residents of the coast, had learned of the camp through the Ti llamook Chamber of Commerce.
We wanted the greater insight into the worl d of
s c ience so volunteered our services. t he members of the Geological Society.
We walked into this world total strangers to A wealth of friendships was in store for us.
My first memory of Murray was in my struggle to keep pace with his s t rides as h e led a group of students from the gates of Pentecost Ranch to a newly opened John Day fossil leaf bed.
It was a good mile or better over grasslands.
I now wonder if
he was the one that discovered this fossil-laden knoll, a deposit that was to draw t he interest of Dr. Ralph Chaney, the famous paleobotonist who went into the Gobi De sert with the adventure writer , Roy Chapman Andrews, after he learned fr om Andrews t he existence of fossilized dinosaur eggs and embryos.
This Pentecostal Ranch fossil
bed was to give Dr. Chaney the opportunity to study a fossil counterpart of floating l eaves on the ponds of today. Life at Hancock was like that of a fraternity or a sorority house.
There was
fun; there was horesplay and there was torment over errors made with the tormented measured on how he reacted .
Murray came out with flying colors .

Just before dinner, Murray would take a couple of students to ferret from

When one leaves the camp those remaining gather to bid him adieu.
When I left,
Murray placed in my hands a Mariposa Lily, pressed between the cardboard of a cracker box and cellophane unquestionably removed from the box, and said "Gaze upon the Mariposa Lily and you will return".
What a unique way to say goodbye.
This was a
prophecy that would come true. Murray was to give the GSOC a glimpse into geometrical patterns so intricate and beautiful that one has to associate them more with fantasy than with reality. Few of this world have experienced this open sesame .
He rigged a camera over a
microscope and photographed diatoms from Crater Lake for a sl ide show at a library meeting.
These colorful forms, so lacy and delicate, can only be compared to the
magnified snowflake.
I hope that these slides have been preserved so that all can
know. It had to be Murray to find music in rocks.
He made a xylophone of shale.
How
many trips he must have made over these rocks and how many he must have rung for pitch to get a full octave or two.
Again this was to be shared with the Society in a
banquet program . And we all know of Camassia, perhaps his greatest achievement and his lasting memorial. Whenever _the Society makes a trip south on the Coast Highway, when nearing North Bend all should scrutinize the sand dunes.

ALONZO W. HANCOCK,
A GIANT OF THE GEOLOGICAL SOCIETY OF THE OREGON COUNTRY by Arthur C. Jones, M.D. Retired from his luncheon address, Dec. 18, 1981
Alonzo W. Hancock was born at St. Joe, Searcy County, Arkansas on March 17, 1884. His own biography states that by the age of seven symptoms of a 'weakness' for the earth sciences began to manifest themselves.
He found limestone slabs filled with
crinoid stems, which he supposed were worms in the rocks.
When he brought armloads
home his father told him they were just rocks and nothing more and bade him take them out on the hillside where he found them!
No more foolish questions.
The family moved to Indian Territory when Lon was nine. clays along the banks of the Arkansas River.
Here he found colored
When he smeared some of these bright
clays on the barn his Dad again discouraged his yen for earth sciences. Lon's education in 'Subscription School' over the next six years was meager, one reason for the family migration by wagon far out to the valley of the Snake River at the eastern edge of Oregon.
They arrived just at harvest time, jobs were plenti-
ful, and the place seemed a paradise to them all.
They settled there.
Best of all,
there was a boarding school just acroll the river in Idaho - The Idaho Intermountain Institute.
Lon found work enough on the campus to pay for board, room and tuition.
Here he studied for four years. clothing, the other of rocks.
On arrival he carried two sacks, one full of No one seemed to care about those nice rocks.
Later Alonzo was directed by one teacher to the Wieser Academy, where he located one professor who was interested in rocks, and willingly spent an hour with the curious lad and his rocks. heard as 'mizpahs'.

This prompted him to apply for work with the U.S. Postal Service
He held this job for thirty-five years, until his retirement from civil service.
Early on he met and married Miss Berrie Horton. Regular hours and vacations gave Lon the opportunity to indulge his interests in the earth sciences.
He and Berrie explored the Oregon mountains and deserts,
especially the Clarno and John Day Formations of central Oregon.
That land of sage,

junipers and penstemon charmed them both, and so did the agates, nodules and occasional fossils which they brought home.
He read everything he could find about the
findings of the early geologists in the fossil beds of his favorite mid-Oregon country, especially Dr. Condon, Merriman, Ira Williams, Dall and many others.
He
doubted the idea that some specialists had voiced that "there were no mammalian fossils in the Clarno formation". cats and camels fascinated him.
The stories of early horses, rhinos, sabre-toothed Lon did a lot of unorthodox digging in many spots
among the colored hills of central Oregon and came up with some real surprises.
He
climbed with the Mazamas for years and was a charter member of the Agate and Mineral Society in 1933 . The extension courses given by several members of the faculty of the University of Oregon, Oregon State College and other schools at Lincoln High School occupied a great many of Lon Hancock's evenings over many years, beginning in 1934.
He received
all of his classroom geology from these sources: Dr. Edwin T. Hodge, Dr. W.D. Wilkinson, Dr. Earl Packard, Dr. Goldenweiser (anthropology), and others.
Of course, when the
Geological Society of the Oregon Country was organized under Dr. Hodge's encouragement and guidance, Lon was among the first to join.
His already detailed knowledge of
sites in central Oregon made him a valuable member for field trips, and his already rich collection of Oregon fossils, agates and minerals became a source of instruction for the members .
He brought some of the most distinctive specimens to the luncheon
meetings and often could identify both rocks and fossils for fellow-members.
In his
home he and Berrie set up a veritable museum of his fossil finds and other treasures, very well displayed, and they invited teachers of natural history subjects in grade and high schools to bring classes therefor visits at which Lon would give talks about these fascinating objects.
The Geesockers were among the beneficiaries of this
generosity. Just when Lon first became aware of the Clarno Nut Beds I do not know, but he was one of the earlier seekers who dug out seeds, leaves, nuts and petrified wood from this Eocene mud flow.
It is located not far east of the Clarno bridge over the
John Day River in a canyon which is north of the road to Fossil. unconformably by tuff s of the John Day Formation.
It is overlain
This proved to be an ideal place
to lead groups of amateur geologists and paleobotanists, and Lon was never one to hide a new discovery from fellow-enthusiasts.
Lon and Berrie camped in that
littl~
draw many times and before l ong they began to lead youth groups there to sense the wonders of paleontology.
The Geological Society had field trips to the location
regularly, and soon plans were laid to make the camp more permanent.

had early shared his hopes for the formation of a museum in Portland to foster the study of all sciences and industries in which science was prominent.
Mr. J.C.
Stevens was also enthusiastic about these plans, and as these ideas took shape most of the members of the Geological Society were taken up with them.
Lon and Berrie,
Leo Simon and Al Vance all worked avidly on plans for this museum-to-be, as did Viola Oberson and many other members of the G.S.O.C. When a house on the grounds which were later to become the Lloyd Center was made available for a beginning of an actual Museum of Science and Industry we all banded together to get exhibits made.
Lon was most generous in sharing his very fine
collection of fossil mammals from central Oregon.
He also instruc ted classes at the
new museum, and regular camp-outs for youth classes were organized during the summer months.
Berrie became official camp cook.
The cook tent grew to be a mess hall,
with a concrete floor which the Geesockers mixed and poured. trips for the camp visitors.

As the
took shape Camp Hancock became a permanent
part of it, appropriately named for Lon and Berrie. Lon's discovery of the mammal beds up the hill to the north of the main camp proved beyond a doubt that there are indeed mammal bones in the Clarno Formation. What he and his helpers found there is another story, but I can vouch for the fact as I have a tapir tooth which he and I dug out one hot sum.mer day the year after Lon had found the mammal beds there.

Those who have
heard him tell the story of evolution, of the formation of those Clarno hills, and of the remarkable animals which roamed the Eocene forest land and savannah will never forget the scenes and vistas which he could picture so vividly.

The route almost completel y en c i rc led two
reg ions of ma jor importance - The Boulder Batholith and the large thrust plate to the east of it, which displaces the eastern front of the Rocky Mountains i nto a prominent bulge eas t of Helena.
In addition to seeing and touching significant t hrust fault
contact s and getting an overview of the Boulder Batholith, including a v iew into Butte's large open-p it copper mine, the Berkeley Pit, we saw the major fault zone known as the Lewi s and Cl ark Line, or "Montana Lineament", which marks the northern l i mit of Basin and Range s t ructure on this continent.
Anaconda Copper Company geologist s briefed us on
the " riches t hill on earth" and the great copper mine and smelter which have declined so dr a s tically in the past year.
Many geologists were saddened to learn t hat mining oper-
ations in the Berkeley Pit had ceased the week before, and the pit is now filling with water .
A much smaller deposit is being quarried a short distance east of t h e Berkeley
Pit.
The organization of the field trip was superb, as was that of t he mee ting itself. The t wo-day symposium on the Structural Geology and Tectonic Evolution of the Northern Rocky Mountain s Fold and Thrust Belt fitted hand-in-glove with the fie ldtrip , and made the entire experience very informative and stimulating.

Two Concepts came from the field trip and symposium which were of particular interest to me.
The first is the now recognized imprint of Basin and Range structure
over the Rocky Mountains as far north as Helena and as far east as the Big Belt Mountains.
It is a topic suitable for another Newsletter article, but suffice it to
say that the Bridger, Madison, Tobacco Root, Lemhi, Beaverhead and Lost River ranges with their intervening basins are examples of the northward extension of Basin and Range structure. The second concept was that of the formation of pediment surfaces . surface~
These cut
which are so prominent on the mountainsides of Montana and Wyoming, have
fascinated and puzzled me for 40 years.
It was a joy to meet several geologists who
have studied them seriously and found that pediments develope only in times of extreme aridity, when the slopes are bare of vegetation, and sheet wash (or solifluction in the case of very cold climates) unimpeded by roots, is the dominant erosive agent. The excitement of this trip has provided me a number of things to write about for future Newsletter issues. Excellent guide books with road logs were prepared for the field trips. Montana Bureau of Mines and Geology, in conjunction
~ith
The
the Department of Earth
Sciences at Montana State University, will publish these guidebooks as Special Publication 86 in the autumn of 1982. I recommend to the membership of the GSOC, and to some future president, that Montana be selected for a forthcoming President's Campout.
After all, most of Western
Montana is part of the Oregon Country as defined by GSOCs, and it is not too far from Portland.
There is a wealth of good guidebooks and road logs which deal with the
Northern Rockies .
The scenery and geology are superb, and markedly different from what
any previous Campout has explored.
The Northern Rockies provide geology at its finest.

210 RUN! THE MARSHUNS ARE COMING! by George A. Deef eldorfer
There must be something to all of those old wive's tales, folklore, and legends about strange things that go squish in the night in marshes.
The literature is
replete with accounts of strange sightings, swirling wraiths, unearthly glimmerings, queer footprints slowly filling with water, noises not made by man or animal. these originating from a marsh.
All
There simply must be at least a shred of substance.
to all this body of reported goings-on. Most likely there is.
Consider.
It would be inconceivably naive for us to
believe, even for a single minute, that our planet was the only one out of all of the dozens, perhaps even hundreds, of other similar round things out there in space that had intelligent life on it.
It is an even bet that they might even be more intelli-
gent than we are, or ever will be.
Anyway, there are probably some guys out there ·
who have a tank of gas, a Visa card and
th~
yen to travel.
So they drop down our way
some night for a visit. Now if you were a visitor from Somewhere Else, even South Somewhere Else, just what would you do when you got in sight of those Golden Arches?
Chances are you would
figure that just maybe you ought to take it a bit carefully at first.
So you cruise
around until you find a nice dark spot and drop in for a soft landing.
There aren't
many Nice Dark Spots left on our turf except for the La Brea tar pits and marshes. The tar pits are out because they are too small and half the people in California drive by them twice a day.
So you land in a cozy ole' marsh, have a spot of tea,
send a Nignt Wire to the folks back home, and send out a scouting party.
While they
are reconnoitering, the kids are splashing around outside the space ship and emitting whoops of joy, which due to profound differences in the local atmosphere from that back in South Somewhere Else, comes out more basso profundo than outraged soprano. The ladies of the ship are busy cooking up a storm on a dual purpose cooking unit which they have set up on a tussock and the smoke and cooking odors drift gently across the bog. At daybreak Hafful Permanente, the village idiot, passes the marsh, hears the kids, smells the cooking and catches a quick glimpse of two of the scouting party in their off-the-rack space suits.
Hafful may be slow witted but he isn 1.t slow footed.
He takes off, and the first of the marsh stories is soon making the rounds.

September 1982 SPECULATIONS ON OREGON CALDERAS - II by John Eliot Allen Professor Emeritus of Geology, PSU Recent published field work has added many new dates and 3 new calderas to those indicated in Oregon (Allen, 1979).
This brings known calderas to 8, with the
6 suggested and hypothetical calderas to a possible total of 14 for the state, com-
pared with the 44 indicated for Nevada (Stewart, 1980j p . 112).

214 OREGON PROVISIONS FOR DAM SAFETY by Daniel H. Griswold
In the Oregon Department of Water Resources there has been established a Dam Safety Division.
The division is staffed by two professional engineers and an
engineering technician. In Oregon, a permit to store water is required for storage over 10 feet in depth and/or containing over 9.2 acre feet in volume.
Application for such a permit
must be accompanied by a set of detailed plans and specifications for the dam and reservoir prepared by a registered professional engineer . Engineers of the Dam Safety Division work with the professional engineers in preparing specifications.
These will vary depending upon the height of the dam, its
location and the hazards resulting from its construction. The hydrology of the watershed above the dam site must be studied in order to design an adequate spillway.
The site geology must be mapped and investigated by
means of borings, pits or trenches to factory.
determine if foundation conditions are satis-
Materials for construction of the dam must be located, sampled and their
engineering properties determined by tests. structure.
The dam may then be designed as a stable
It is required that the dam be built under the supervision of a lisensed
engineer. The Dam Safety Division has administrative rules and minimum design requirements and operates according to them.
Oregon has not published a manual for design
of dams according to these requirements as Colorado has done. The Oregon Dam Safety Division wants the professional engineers to design the dams.
The engineer's license and ability are respec ted.
Personnel of the Division
wish to inspect the site preparation and examine materials in pits and cores.
They
review the plans of the proposed dam with the professional engineer and give approval of construction when satisfied that safe conditions have been demonstrated.
Only
when the application is approved can construction begin. A representative of the Corps of Engineers reported that the Corps examined and reported 48 non-federal dams in Oregon. of poor material, three had inadequate problem.

This is their function and is as far as far as they can go. I discussed the status of dams with the head of the Oregon Dam Safetyi
Division.
In his estimation, the Possible Maximum Flood estimates by the Corps are
too high and the spillways of the three dams are not inadequate.
He did not · comment
on the three remaining dams considered hazardous by the representative of the Corps of Engineers. Ed. note:

IT RAINED ON OUR PICNIC BUT WE DIDN'T GET WET by Peigi Stahl Actually, it had stopped raining by picnic time but the grounds where we held the picnic last year were all drippy and dismal.
Thanks to Alpenrose Dairy the GSOC
Annual Pot-Luck Picnic was held in the Ice Cream Parlor, a delightful little building in Alpenrose Village. Claims were made that the food was even better and more abundant than ever . Perhaps because it was augmented by delicious vanilla ice cream, courtesy of the Alpenrose Dairy people. After the tables were cleared Dr. Jones led the singing, Reba and Lloyd Wilcox sang a new Geesock song they composed on the way home from Campout, and 'Chief Shortcake made a brief appearance. By 9:30 everyone was on his way home, taking with him the leftovers and a pleasant memory.
Walter (Whit) Whitney quoting the February '81 issue of Oregon Geology 'Smithson said "You know, one pebble moving a foot in two million years is enough to keep me really excited."

Remember when geologic time was almost inconceivable? that we are geared to the national debt.

218 A NOTE FROM THE EDITOR
This is the Campout issue of the Newsletter. At campout this year the common practice of traveling by caravan was abandoned and the four main trips were accomplished by bus. The minibus, a 15 passenger vehicle, brought its full contingent from Portland and conveyed them not only on the field trips but also to restaurants, shopping, etc. The others attending the campout arrived by private conveyance and were transported on the four major field trips by a chartered Trailways bus. The geology covered on the field trips is not included because that has been well documented elsewhere.
WE TRAVEL BY BUS by Bob Richmond 8:15 A.M. SUNDAY, AUGUST 1 Our first field trip of the President's Campout.
The Trailways bus has arrived
at the Sportsman's Motel, about half its seats filled with noisily chatting GSOCers who had boarded at the KOA campground, and we quickly file aboard, stowing our gear and taking the remaining seats.
We are greeted and instructed in orderly exiting and
seat rotation:- At all stops the seats on the right side of the aisle are to empty first, and the occupants will move back one seat on reboarding. moving foreward one seat at each reboarding.
Those on the left
By about 8 : 25 the minibus and two pas-
senger cars are lined up behind us and the big bus pulls onto Highway US-97. Our first stop comes very quickly at Shevlin Park, on Tumalo Creek.
Lunches and
extra jackets have mostly been stowed overhead, ·but any other carry-on gear not needed for this stop is hastily thrust onto the next seat back, or which side of the aisle one occupies.
foreward, depending on
In a few hectic moments the right side of the
bus begins to empty in what would be an orderly fashion except where blocked by someone who must stand in the aisle to stow or unstow on the overhead shelf, or by those who can't chuck their gear in the seat behind because the knotheads in the next seat can't chuck their gear because the knotheads behind them haven't figured it out yet either.
But none of us retain more than brief temporary status as knotheads and are
soon overcome with intelligent action and the bus is emptied. We learn early-on that this will be a tuff trip; there is the Desert Springs Tuff, overlain by the Tumalo Tuff, the Lava Island Tuff and the Shevlin Park Tuff. And if that isn't tuff enough, we will also run into some tuff stuff in the upper Deschutes Formation. After frequent stops we start the winding climb up the east slope of the Cascades toward McKenzie Pass.
Lunch is at Lava Camp Lake, where the bus barely navagates an

entrance road designed for much smaller craft.
We eat, and again underway come
quickly to McKenzie Pass, which is almost totally enveloped in clouds, so we continue on.
The bus driver gets a workout on the narrow, crooked roadway and is glad to have
a brief rest at the Craig Memorial and Craig Lake.
Then we begin the tortuous descent
down Deadhorse Grade, with its ever tightening curves, narrow roadway and nonexistant shoulders.
The unsuspecting bus driver, not having seen this route before,

he know that the worst may be to come, for he has not yet navigated a curve marked at less than 15 MPH, and ahead there lies in wait at least one curve marked down to 10 MPH. Now we come to a long straight stretch (at least 8 bus lengths long) , and we stop at the trailhead to Proxy Falls.
The bus driver reaps a much needed recess and
we hike a short half mile to view both the Upper and Lower Proxy Falls.
Then, finding
the hour is late, it is decided to return the way we came, with our bus driver chagrined to think that he must fight his way back through all those curves again. TUESDAY, AUGUST 3 We again board the bus, and will take the same seat positions we had at the end of the last trip.
We had hoped to have the same driver, but learn that he is resting
by driving a regular scheduled run to Klamath Falls and return.
Today our leader is
Larry Chitwood, Geologist for the Deschutes National Forest headquartered in Bend. We get underway promptly, and since we are now experienced seat changers, the rotation system works smoothly for our many stops, including lunch at Todd Lake, a picturesque mountain lake with Broken Top projecting its jagged peaks over the north rim of the lake in the background. Lunchtime is perforated with discoveries of native flora and fauna which abound in the wet meadow near the lake's outlet, and we take a reluctant leave of this place, having more seats to rotate, more miles to ride and more sights to see. Again it gets late and we, having found too much of interest early in the trip, have no time for more
and must reluctantly return by the shortest route.
And so
back to the barn it is.
THURSDAY, AUGUST 5 We will again take our positions where we left off on the last trip.

The bus leaves.
Today we make many stops where we see a deep dry river canyon, faulted terrain and dry river beds, numerous fault-formed grabens, horsts and pressure ridges, and such prominent features as Horse Ridge, Pine Mountain, Newberry volcano and Bear Creek Buttes.
Everywhere we look, nothing but geology.
Our lunch stop is in the picnic area alongside the river a short distance below the Prineville Reservoir Dam.
We are now seasoned hands at boarding, rotating on exit,
and reboarding, but still haven't solved the problem of quickly finding the lunches we stowed over seat number 3-right when lunch time finds us in seat 9-left.
But in time
we overcome this obstacle and have our lunch under the massive cliffs of multi-layered basalt with neatly vertical columnar segments
interrupted by columns leaning, bent
or twisted in many directions. More geology all the way to Smith Rock State Park.
We spend some time here with
cameras and then we assemble for a very brief run to the next stop, a small store only a few hundred yards south of the park where we line up outside the screen door and single file in to buy huckleberry ice cream cones.
The cones are heaped with single,
double or triple scoops, depending on the appetite, caloric tolerance or loose change of each individual.
The ice cream counter is well stocked and efficiently manned in
the tight quarters of the store interior, for we were expected.
Our thoughtful leader,
Ruth Keen, has reconnoitered the place and its wares, given advance notice of our arrival and rightly concluded .that this is an appropriate pause on a hot afternoon such as this.
We are refreshed, revitalized, and to heck with the calories; nobody's
counting. On board again we proceed to the site of the diatomaceous earth mining facility of the Oremite Mine, then back to Terrebonne and home on 97.
SATURDAY, AUGUST 7 Today we have to get up before breakfast, for the Trailways bus comes first to the motel, and .heading north, boards the campground contingent last. north through Redmond, then Sisters.
We continue

THE MINIBUSERS ON THE PRESIDENT'S CAMPOUT by Jean Boe There was something special about the minibus group, close, and in accord most of the time. Driver Ray Seeley piloted us safely, taking good care of us and our trappings. Hazel Newhouse did an incredible job of keeping us organized - on and off the bus, in and out of places, and on time.
Bob Gamer helped to make us aware of the scenic

A birthday dinner was held at Shari's for Ray Seeley and Jean Boe whose birthdays were August 1st and 2nd. While visiting Paulina Peak, on the Newberry Crater rim, we encountered a big pulsating truck with several large antennas.

MT. HOOD - PORTLAND'S OWN VOLCANO by Robert L. Gamer Engineering Geologist, Foundation Sciences, Inc. Since many GSOCers got a spectacular view of Mt. Hood on their way home from the 1982 Campout, a word about the geology of this mountain is appropriate.
Mt. Hood
has been of special interest to Portlanders ever since the earliest days of the city's existance.
In those days, smog was less common and a view of Mt. Hood looming above
the horizon was more or less synonomous with the City of Roses. From the bottom to the top, Mt Hood, like most of the grand volcanoes of the Oregon Cascades, consists of - 1) a base of coalescing shield volcanoes, 2) a cone of alternating layers of andesite lava and fragmental debris burying the shield, and 3) a dacite dome poking out of the peak.
Also , like most of the other Cascade peaks,
its sides and top are deeply carved by glaciers . THE BRITISH NAVY Many people think that the mountain's name came from a vapor which resembles a "hood" that hovers around the summit. appropriate.
From this point of view, the name is most
Although the cloud does resemble a hood covering a beautiful lady's
head, the resemblance is purely coincidental and has nothing to do with the mountain's name.
Mt. Hood was named by Lieutenant (later Captain) William Robert Broughton,
commanding the H.M.S. Chatham of His Most Royal Britanic Majesty's Fleet. Lt. Broughton sighted the mountain from the Columbia River near t ·he mouth of the Sandy River and named it after his boss, Viscount Samuel Rood, who was a sea-going member of the Irish peerage. Hood was an admiral of the Blue, and a scourge of all French ships that plied the Seven Seas. It is presumed that Lt. Broughton earned several "Brownie Points" by this wise course of action. STATISTICAL Mt. Hood is the second most often climbed mountain in the world; the first being, of course, Mt. Fujiyama in Japan. associated with the fresh air of Portland. Oregon.

It is located in the High Cascades
The High Cascades occupy a graben (down-faulted trench).
As the area of this trench sunk, the resulting depression was filled up by eruptions from the volcanoes.
The filling continued until the sunken area actually got higher

There
During the Frazier
Glaciation, ice covered the entire mountain.
CONCLUSIONS During the course of its long history, Mt. Hood has gone through many geologic stages.
All of these stages can be seen some place in the volcanic terrain of
Oregon.
On their campout near Bend, The GSOCers could observe these different stages
at the different places
they visited.
In the beginning, Mt. Hood started out as
simple volcanic shields similar to the shields at Belnap Craters at the McKenzie Pass.
Later, as it grew upward, it probably became a cinder-cone like Lava Butte
south of Bend.
Then, as lava flows alternated with ash falls, Mt. Hood built up a
composite cone like Mt. Jefferson.
Perhaps, at different times, it resembled Mt.
Saint Helens before and after the 1980 eruption.
Certainly, as a dacite dome grew in
its crater, there had to be some resemblance to the dome of St. Helens. Mt. Hood has been glaciated like so many of the Oregon peaks .
In the past
Perhaps in the future,
after another ice age or two, the mountain will be worn down and will look like Three Fingered Jack. REFERENCES Allen, J . E. "The Magnificent Gateway", 1981 Federal Writers' Project 11Mt.

GSOC INVASION GOOD FOR BUSINESS by correspondent M. Steere BEND, OREGON:
Between 60 and 70 members of a gang from the other side of the
mountains infiltrated Bend on Saturday July 31st and became entrenched for a week in ~he
Sportsman's Motel and the KOA Campground at the north end of the city. The whole gang was first noticed by Bend residents on Saturday evening
descending Pilot Butte.
After wandering through town as though lost, the gang finally
took over Drake Park where the members set up tables and spread out an abundance of casseroles, salads, and watermelon.
Bend's Air Squadron, doing maneuvers on the lake
at Drake Park, kept an eye on the group and reported that the gang's appetite augered a raid on the city's food resources.
So a watchful eye was kept on the gang members
during the week as they invaded grocery stores and restaurants.
Several Bend residents
reported holdups in lines at cash registers, but it isn't known at this time if guns were pulled. Each morning the gang mysteriously departed in buses and cars and returned at 5:00 p.m.
Green and white signs on their vehicles bearing the letters "GSOC" aroused
much speculation among local residents.
One Bend resident said the gang seemed
harmless and he thought the signs stood for "God Save Our Country ."
Another, on
observing one elderly gentleman with two canes hop gingerly into a car with a young woman, said he was sure the sign meant "Geriatric Society Out Cavorting." On various evenings the gang held camp meetings.
The first was under the cover
of the carport at the Sportsman's Motel, where the managers were held hostage for two hours.
The gang leader, a woman, was recognized by old-timers of Oregon as Dr. Ruth
of State Wide Education.
Her sermons seemed to stress BEING ON TIME IN THE MORNINGS.
One gentleman, referred to as Chief Shortcake, was heard to say he had grown up in a wigwam in Bend. On subsequent evenings the group met on the grassy slope of the KOA grounds. Music was always first on the agenda.
One evening the whole group, accompanied by
fiddle, guitar, and harmonica sang about picks, shovels and nodules.
On another
evening a group of lady songsters gave their rendition of the gang's message to the world.
At first the Bend observers, spying from the treetops, thought the gang might
be a group of traveling musicians, but this idea was soon abandoned on hearing the product.

One woman in the gang, who kept bringing bottles of wild flowering plants to the camp meetings, was finally identified as a health freak testing herbs to induce longevity.
Each meeting included testimonials by various members and ended in a
scuffle around a table of food. Bend spies were staked out to observe the final camp meeting when a number of gang members received awards, presumably for loyal service.
The flower lady received
a crown made of herbaceous materials which, on donning, caused her to cry out in pain. The gentleman known as Chief Shortcake received a stunning headdress of peacock feathers.
There were many other awards, including a leaking jug of water, said to be
the headwaters of the Deschutes River, that caused one woman to nearly drown.
The
gang's leader, Dr. Ruth, was handed a scroll which, when unrolled, revealed a diagram of bright colored layers.
Bend spies recognized it at once as layers of earth around
Bend and suspected Dr. Ruth of planning to rob the area of gold. The mysterous gang departed on Sunday morning, August 8th.
According to the
Bend Air Squadron from Drake Park Lake, most of the people headed westward over the mountain passes, but a few ended up in a cinder pit south of town, and some others were observed moving toward the Steens in southeastern Oregon. When canvassed for opinions the following week, the majority of Bend residents agreed that the GSOC gang was probably harmless, and that it came primarily to eat, and that it was good for business.
TRIVIA by Peigi Stahl October is the month for hobgoblins and other mischievous little people, and believe me, they all have been helping me with the Newsletter (and they're not on the Staff either).
Murphy's Law has prevailed throughout.
I fell apart before campout and so far haven't found all the pieces. the Newsletter is late and probably full of errors .
Please forgive.

ALBERT DUNBAR VANCE,
A GIANT OF THE GEOLOGICAL SOCIETY OF THE OREGON COUNTRY by Arthur C. Jones, M.D. Retired, from his luncheon address, Dec. 18, 1981
Albert Dunbar Vance was born April 11, 1883, in Decorah Iowa. Engineering at the University of Wisconsin.
He studied Civil
He went on a government land survey to
Big Horn Basin in Wyoming in 1906 and was appointed U.S. Deputy Land Surveyor for Wyoming later that same year.
His survey of twelve townships was completed in 1908.
He also worked on the Shoshone Reclamation Project for the Reclamation Service. Al moved to portland in 1910, working for the City of Portland as a surveyou Al moved to Portland in 1910, working for the City of Portland as a surveyor until January, 1916.
After almost a year of field mapping for the U.S. Forest
Service, Al turned to work in the ship-building industry, engineering ship-ways for two companies that built ships for use in World War I, ending in 1920, when he was Superintendent of Construction for Coast Shipbuilding Company.
After a year each
with the Portland Dock Commission and the Port of Portland, he returned to city service, working in various capacities, and was appointed Assistant to the City Engineer (Wm. A. Bowes) in June, 1939 .
A position he held until his retirement.
Al Vance and Florence J. Oviatt were married in January, 1911.
They had a
daughter, Mrs W. Hiney, Of Los Angeles, and a son, Albert D. Vance, Jr. Al was always deeply interested in geology and so was attracted to the University of Oregon Extension Service classes taught by Dr. Edwin T. Hodge.
He
naturally joined the Geological Society when it was organized in the Spring of 1935, and became a regular attendant on the field trips and lectures as well as at the informal luncheon meetings. Through these contacts Al and I became very well acquainted.
He was most
intrigued by the many fine fossils of marine mollusks which we could find along the Astoria Formation Miocene exposures on the Northern Oregon coast and soon had assembled a fine collection of these shells, and of the Pittsburg Bluff Formation Oligocene fossils, including a good suite of crabs from both horizons.
He showed me
characteristics which differentiated the many pelecypods - anadera, acila, spisula, tellina and nemocardium, just to name a few . It was my good fortune to become Vice-President of the Geological Society the

year Al was President, 1937-1938.
We scouted field trips together several times,
both to Central Oregon and along the Coast, and each trip was a delightful experience. That year the weather was unduly moist, and we had so many wet field trips that summer that we came to calling it "'l'he rain of Al Vance".

Al never tired of sharing his rich knowledge of geology
with anyone who showed a real interest, and he was always kindly. As often happens, people of keen imagination also have the qualities of the poet as well.
Albert Vance was a poet.
The inspiration and wonderment which he
found in the contemplation of cosmology, the evolution of living forms and of man can best be conveyed to you by the f olowing poem which he wrote and was printed in the March 1948 Newsletter:BEGINNING DAY Time is only relative And in the infinite plan An instant of eternity Is a billion years to man. Out of the formless void, Steeped in fathomless night, God from beyond the beginning Created the living light. Swirling neutrons and protons By fission in reverse He gathered to form the atoms and builded the Universe. Planets, suns and galaxies Moved their appointed way And the evening and the morning Marked the beginning day ---A. D. Vance
The great scope of his remarkable vision of how evolution has proceeded through the eons alone would be enough to justify the designation of Albert D. Vance as one of the Giants of the Geological Society of the Oregon Country.

"- - - and the speaker tonight is - - -" by Ralph S. Mason Over the years I have given many talks to all sorts of groups and, in some cases, non-groups.
During
th~s
time I have had many enlightening experiences, most of them
pleasurable, but alas, some quite the opposite .
For what it is worth, here are some
observations on public speaking, audiences, and program chairmen.
Since you almost
certainly have either been, or will be, a speaker, a member of an audience, or a program chairman, there is something for you in the following paragraphs. I would like to get a few pet peeves off my chest right away and then we can coast along on anecdotes and constructive suggestions .
At the top of my list is the
program chairman who calls me up and asks for a program that "will only take twenty minutes of your time" for an evening meeting of six or eight club members at a place thirty miles away.
That twenty minute talk actually involves the following :
1) Putting a hold on that date and making sure the car will be available (I live in a one-car family); 2) Preparing for the talk, usually about a two hour job; 3) Getting ready and travelling to the meeting place, and allowing plenty of time to find it, get parked , and get set up; 4) Sitting through either a business meeting, a meal, or a subsidiary program, or all three ; S) Giving the twenty minute talk (which usually lasts about forty-five minutes due to the questions afterwards) ; 6) Gathering up your gear and eventually, after possibly making two trips, getting it all back in the car; 7) Driving home; 8) unloading, and if slides were shown, re-distributing them into their proper files. six or more.
All this adds up to not less than four hours, and often it takes
Twenty minutes -- hahl
Close on the heels of my No. 1 peeve is the program chairman for some service group who plainly indicates that I "owe" it to his organization to give them a program.
This request usually comes in the day before the program is wanted and rarely
is any offer to reimburse travel expenses made.
With driving in the city costing
somewhere above twenty cents a mile you would think that an offer to defray expenses would be made. So much for my main gripes .
I greatly enjoy speaking to groups, and·
participating in radio and TV programs. it all worth while.

I once showed my notes to the person who was to introduce me -- and he

242 THE DESCHUTES FORMATION by Robert L. Gamer Engineering Geologist, Foundation Sciences, Inc.
The Deschutes Formation has a special significance to the Geol0gical Society of the Oregon Country because of Dr. Edwin T. Hodge's work on the formation. founded our Society.
Dr. Hodge
He nursed it along during its formative years and gave it the
essential push it needed to make the Society what it is today.
During this period
Dr. Hodge published the first authoritative descriptions of the Deschutes Formation. Any geologist seriously working with the formation is wise to first consult Dr. Hodge 's papers on the subject. The members of the Society who returned to Portland from last swnmer's campout along Highway 26 could get a good look at the Deschutes Formation.
Here, the road-cuts
from the top of the Metolius Bench to the waters of the Warm Springs River expose a large part of the formation, strata by strata. LAND FORMS The Madras Basin lies east of Green Ridge, roughly between Redmond and the Mutton Mountains.

East of the river the drainage more or less parallels
the river in a sort of a dendritic pattern.
The upper reaches of the Metolius River,
a tributary of the Deschutes, parallels the Green Ridge Fault.
Most of the area
consists of volcanic plateaus that form on the surface of lava flows or pyroclastic beds.

Before this diversion these streams flowed directly into the Pacific Ocean.

TRIVIA by Peigi Stahl
In order to fill up vacant spaces in this publication I have been pursuing geological information by perusing assorted scientific publications.
Much of what is
written, you must realize, is well beyond my ability to understand, however, on occasion I do come across bits of information that I can pass along to our readers. One such article appeared in the October 9, 1981 issue of the magazine .. Science".
It deals with earthquakes in the eastern part of the United States.
These have different causes than our far western seismic and volcanic activities, believed due to
th~
Pacific Plate sliding under the North American Plate and causing a
bit of a ruckus now and then. In the winter of 1811-1812 near New Madrid, Missouri three major earthquakes and their aftershocks released as much seismic energy in three months as all of the earthquake activity in the United Stated usually does in SO to 100 years, causing considerable geologic
havoc~
What has bothered geologists through the years is that they have not been able to find any visible signs of a fault or faults. Now a group of U.S.G.S. researchers using seismic reflection profiling - a technique that bounces acoustic signals off the boundaries between different underground rock units - claim to have found a set of parallel faults which have approached to within a few hundred meters of the surface in Tennessee, and a major fracture zone beneath one kilometer of sediments in north eastern Arkansas.
These faults are
located in the active seismic zones and seem to be responding to the crustal stresses that are thought to drive earthquakes in the central U.S. The New Madrid fault zones have not always behaved the way they do today.
The
displacement along one of the faults shows that about 75 million years ago tensile strength was pulling the fault apart and later the stress reversed and began to compress it.
It is suggested that these faults have been alternately pushed and pulled
since the stretching of the earth's crust formed the first of them about 500 million years ago.
That was probably at the time that the ocean that came before the present
Atlantic Ocean was being formed to the east by the tearing open of the continental crust.
The crust of the New Madrid area felt the same stress and pulled apart
slightly to form a narrow sunken rift, and ever since has felt a squeeze whenever the North American plate. banged up against another moving crustal plate and a stretching when continents have split open to form oceans. Scientists feel that the present compression, caused, possibly by the drag of

the continent over the mantle, has caused the New Madrid faults to slip catastrophically every 500 to 1,000 years in recent t i mes . Another ancient fault zone has possibly been defined in southwest Virginia by a moderate earthquake in 1897 and eight microquakes and four larger quakes detected since 1958 .
Elsewhere in the east things are considerably mor e muddled, with
researchers trying to locate possible underground faults and to determine the direction of slippage. IJIJfl
"DISTINGUISHED CITIZEN" AWARD GIVEN TO LOUIS E. OBERSON The Environmental Education Association of Oregon award was presented to Louis E. Oberson on November 2nd at Camp Howard by Ernie McDonald, Environmental Education Officer of the USDA Forest Service.
It reads: "Distinguished Citizen
Environmental Education - Louis Oberson has contributed significantly to Envirenmental Education in Oregon". Louis Oberson taught biology to highs chool students for thirty-nine years and has worked with sixth graders in the Outdoor School Program for thirteen and one-half years. He has been president and reginal director of the Xen's Garden Club, president of the Geological Society of the Oregon Country, director of the Audubon Society, director of the Leach Botanical Park, and a member of the Nat ive Plant Society of Oregon. He feels that the one hundred thousand 6th graders who have participated in Multnomah County's Outdoor School Program and those who worked for the program have a ll helped to make the school successful 1
He has tried to communicate to all an appreci-
ation of all the wonders of soil, water, plants, and animals. The Camp Howard staff presented this original poem to him upon his retirement this year as soil consultant: His eyes were so keen as he sought prey from so high His territory vast as he covered the land His song was so bold as he spoke loud in cry Using wings for his travel as he soared through the sky . Like the eagle who touches all of our hearts Like the doe that nurses her faun You were the bold and the keen like the eagle You were kind like the doe to her faun You were open to share all your knowledge But we~re sad to see that you're gone. Yes, we miss all your wonderful qualities and we cherish the ones left behind But we'll think of you often at Howard 'Cause we know that you are one of a kind.
