EOU Geology

Phi Beta Rock, the EOU Geology Club, in Hawaii (2008)


2014-2015 will be the last year for the EOU Geology program.  We’ll be offering introductory geology courses for student wishing to fulfill general education requirements.

Our Fall 2014 Weekend College courses will include: Gold Mining in Eastern Oregon, John Day Fossils, and the geology of the Wallowas.  Our Spring 2015 weekend colleges will include Earthquakes and Volcanoes, Geology of the John Day country, and Geology of the Oregon coast.

Eastern Oregon University is located in the La Grande Basin, a graben in the Blue Mountains of Eastern Oregon. Our area has been referred to as “a geological wrecking yard” of 240-200 million year old tropical volcanic island arcs, 150-100 million year old granitic batholiths, 40-20 million year old andesitic and rhyolitic volcanics, and 16-2 million year old Columbia River flood basalts and Powder River volcanics, all deformed by block faulting and carved by Pleistocene glaciers. We’re close to the Wallowa and Elkhorn Mountains, Hells Canyon, the John Day Fossil Beds, the Owyhee volcanic area and a lot of other spectacular geologic sites.
