Where
Are We?
Eastern Oregon State College 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 20-13 million year old
Columbia River flood basalts and andesites, 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. And, the Cascades,
the Oregon coast, Yellowstone, Glacier National Park and other areas are
within a day's drive! It is a great place to study geology!
