Announcing the Central Oregon Geoscience Society

The Central Oregon Geoscience Society (COGS) has formed as a central-Oregon based, non-profit organization promoting a greater awareness and understanding of the geological sciences through technical presentations, field trips and educational outreach to schools. They plan to have eight presentations per year, as well as field trips in the late spring through early fall. Presentations are held at Deschutes Brewery Tap Room (upstairs), 1044 NW Bond Street in Bend. Join them at 6:00 PM for food/beverages and presentation at 7:00 PM.

For Our Retired Members: Take a Geology Class!

For Our Retired Members: Take a Geology Class!

by GSOC Past President, Bo Nonn

Why not audit a class at PSU? It's free, practically, and you get to hear the same great professors who've addressed our Friday night meetings. I've been auditing mostly geology since I retired, over 30 to date, from entry-level to heavy-duty senior/grad. You can arrange with the instructor on how deeply you want to get involved, from just sitting in on the lectures all the way to labs, quizzes, term papers and exams.  If you're interested, read more!

Geology of Eastside Portland and Johnson Creek

Geology of Eastside Portland and Johnson Creek

Moments after the election of the new GSOC board at our February 9th meeting, President-elect Paul Edison-Lahm addressed a near-record crowd with his presentation “An Amateur's Guide to the Geology of Johnson Creek and Eastside Portland.” He explained that since a creek cuts down through vegetation and construction into layers of earth otherwise unseen, the rocks in the creek can tell us the geologic history of the surrounding countryside. Grey basalts and dull orange quartizites, found in the Reed College Lake near his home for example, are clues to earlier epochs of catastrophic volcanism and icy inundation.

GSOC Charter Member Lon Hancock First to Discover Vertebrate Fossils in Oregon's Clarno Formation

GSOC Charter Member Lon Hancock First to Discover Vertebrate Fossils in Oregon's Clarno Formation

By Viola L. Obserson, GSOC President 1984. Reprinted with permission from Oregon Geology, Oregon Dept. of Geology and Mineral Industries, December 1979.

Paleontologists the world over know of the work of Alonzo Wesley "Lon" Hancock (1884-1961). Professional men from the universities and museums of the world came to his door to study the fossils he found. He considered himself an amateur, attained no college degrees, and published no scientific papers, but the fossils his persistence enabled him to find have been the subjects of numerous papers, master's theses, and doctoral dissertations. And part of the geologic history of ancient Oregon has had to be rewritten because of his discoveries.

Oregon Gems of the Rice Museum

Oregon Gems of the Rice Museum

Rice Museum curator Leslie Moclock is in charge of the museum’s education curriculum. In the course of her educational presentations, she finds that kids always ask deceptively tricky questions like, “Why are minerals the color that they are?” Moclock enjoys this part of her work because answering these questions opens doors to doing research. Examples of research topics she has pursued include two famous Oregon gemstones, opal (notably from Opal Butte in Morrow County) and sunstones (from Ponderosa and Plush area mines).

A small party of GSOC members braved the iffy weather on September 9, 2017, to take a new view of Mt. St. Helens, aboard a helicopter owned and piloted by Hillsboro Aviation Company, on a trip of geologic discovery organized by Sheila Alfsen. The flight was launched from North Fork Survivors tourist complex on Spirit Lake Highway east of Toutle, Washington.

Future Solar Eclipses in Oregon

Future Solar Eclipses in Oregon

We will never see another total eclipse in our lifetime unless we leave Oregon, however eclipsewise.com has links to small scale world maps, each showing paths all eclipses in a chosen 20-year interval, with the date of each.

If the above website yields a date you are interested in, use the following Nasa Eclipse Website map with the exact date substituted for yyyymmdd. This will display a Google map with the eclipse path that you can zoom in on.

New Info on the Origin of Bimodal Volcanism on Oregon’s High Lava Plains

New Info on the Origin of Bimodal Volcanism on Oregon’s High Lava Plains

April’s Friday night lecture was given by a truly distinguished Oregon geologist and highlighted recent research into an area that has long intrigued geoscientists about Oregon. Dr. Grunder has led a team of researchers, including PSU’s Martin Streck, exploring the possible origin of the magma that has peppered Oregon’s High Lava Plains geologic province in the last 12 million years. This magma includes both rhyolite and basalt eruptions in a swath of territory between Steen’s Mountain region to the southeast and Newberry Volcano to the northwest.

Thomas Condon's Fossil Collection

Thomas Condon's Fossil Collection

Professor Emeritus and Condon Collection Curator Dr. William Orr spoke to GSOC on May 12 about Thomas Condon’s fossils. This collection was assembled for teaching and reference and ranks with the best collections for stratigraphic continuity and taxonomic breadth. Many specialists from around the world come to the University of Oregon to study its fossils.
