Friday Night Lecture: Teaching and Doing Geology in Southern Oregon

Frank Hladky, Oregon Registered Geologist and Geology Instructor will discuss Getting the Science Right: Teaching and Doing Geology in Southern Oregon. Teaching geology to youth requires clarifying the philosophy of rational thought. Geology, like other sciences, relies on evidence to substantiate interpretations. Utilizing vignettes from geological field studies in southern Oregon, Mr. Hladky shows how multiple lines of evidence leads to an understanding of the natural world with greater clarity.

Erratic Boulders — Legacy of the Ice Age: Talk by Rick Thompson

  • PSU Cramer Hall

At the end of the Ice Age when the Lake Missoula Flood roared across the landscape, the floodwaters carried with it granite and other boulders. These rocks, referred to as erratics, were encased in the floating sections of the broken ice dam and distributed along the path of the mighty waters from Montana to the Pacific Ocean. Rick Thompson of the Ice Age Floods Institute will tell about the ongoing hunt for these iceberg erratics in the Portland/Willamette Valley area, explain how to recognize an erratic, and discuss ice age floods around the world.

Friday Night Lecture: Eyewitness Chronicles of Mount St. Helens

  • Portland State University, Cramer Hall

Dr Richard Waitt from USGS CVO will elaborate on his recent book In the Path of Destruction: Eyewitness Chronicles of Mount St. Helens: "The May 18, 1980 eruption of Mount St. Helens was an international sensation. Those who lived through it never forget the experience. A geologist with intimate knowledge of Mount St. Helens, Richard Waitt chronicles the eruption story through unforgettable, riveting narratives—the heart of a masterful chronology that also delivers engrossing science, history, and journalism." (Washington State University Press)

PSU Has Discontinued Free Evening Parking. GSOC has just received a communication from the Portland State University Geology Department office that stated “Please be advised that beginning Monday, September 19th, all PSU parking facilities will require payment or valid permit at all hours, all days, except for university holidays. Vehicles found on campus without proof of payment or valid permit will be subject to citation.” This means that we will no longer be able to park for free in the PSU parking garage on Friday nights.

FOR DRIVERS
The cheapest option is to look for nearby on-street parking. If you find a spot it's $2.00 per hour until 7:00 pm and free after that. For people willing to walk a few blocks, either PSU Parking Structure 3 at 12th and Mill Street or the Shattuck parking lot at Broadway and College Street will charge $2.50 per hour. The structure we have been using, PSU Parking Structure 2, will now charge a flat $7.00 for the evening, with no hourly rate.  A useful map is at the PSU website.

FOR PEOPLE USING PUBLIC TRANSPORTATION
Look for a convenient park and ride near a MAX train or bus stop. The #19 bus and the Orange Line MAX drop you off within a block or two of PSU. The bus gets scarce after 9:00 but MAX runs pretty frequently.

Friday Night Lecture May 13th: Dr. Bill Orr — Lagerstätten!

A Lagerstätte (German from Lager 'storage, lair', Stätte 'place'; plural Lagerstätten) is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues. These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying decomposition.

Dr Nancy Price, Portland State University

Addressing Tectonic Questions from the Perspective of Rheology*

*Rheology: the study of the flow of matter

There are two ways in which structural geologists look at the formation of mountain belts and transform plate boundaries. The first is to describe the folds and faults as rocks reacting to events, and to study the deformation and mineral growth as a reaction to these events. The second is to study the material properties and deformations of the rock layers as a response to stress fields, and to explain the formation events in terms of these properties. In effect, the strength and deformation behaviors of the rocks control the formation of the mountain belts and fault zones. This is the perspective of rheology. In this lecture, Price will show examples of viewing rocks from a rheological perspective and interpreting tectonic history in this light.
