EASTERN OREGON GEOLOGY
We have learned a tremendous amount about the geology of Eastern Oregon in the past few years thanks to the work of the Oregon Department of Geology and Mineral Industries and the faculty and students of Boise State University, Portland State University, Whitman College, the University of Oregon, Oregon State University, Washington State University, Eastern Oregon University, and others.
The intent of Eastern Oregon Geology is to provide an on-line journal where new discoveries, particularly those by undergraduate students, can be highlighted and made available to a larger audience. We welcome your comments and suggestions for improvement!

VOLUME 1. Gravels. January 2002
Editor’s Note: John Eliot Allen wrote about the Paleocene auriferous paleotorrent in Northeast Oregon . These papers focus on gravels that may have great significance to understanding stream flow in the Grande Ronde Valley
area during the Miocene.

VOLUME 2. Wallowa Lake. September 2005
Editor's note: This issue is devoted to the EOU Geology program's studies of Wallowa Lake which have been made possible due to the generosity of Eastern's former president and first lady, David and Carolyn Gilbert. The Gilberts provided us with their boat, lodging, and meals, plus lots of stimulating conversation, making this a wonderful place to do research. Along the way, our students have figured out how to digitize depth data, program it into MapInfo and Vertical Mapper, and produce beautiful color charts of the lake floor. And, they have learned that equipment often breaks and how ingenuity and resourcefulness play an important role in fieldwork. We've learned a lot, but, as with all good research, we've revealed even more about what we don't know about the floor of Wallowa Lake. Enjoy!

VOLUME 8. The late Pleistocene Airport Lane Fossils-- September 2011
Editor’s Note: This volume features a series of short papes describing the Ice Age fossils that were found near the La Grande Airport in January 2010. An article written by Amber Glaze for The Observer was picked up by the Associated Press and featured in every major paper in the United States and on Oregon Public Broadcasting. A follow-up article appeared in EOU's alumni magazine, The Mountaineer.
