on the “Latest Pleistocene Geologic History of Upper Grand Coulee” by Dr. Patrick Spencer will occur this Thursday, November 17, at 7 pm on the Eastern Washington University, Cheney Campus, in Science Building Room 137.
Dr. Spencer is a professor of geology at Whitman College, Walla Walla, Washington. He will present a summary of his recent work on fine grained sediment in Upper Grand Coulee, including analysis of grain size distribution, sedimentary structures and radiocarbon age dates on key localities, suggesting that some of the sediments accumulated in a calm-water setting, possibly in a lake behind a moraine-dam. Grand Coulee was then swept by Missoula Floods, leaving behind a record of high energy processes.
The lecture is sponsored by the Cheney-Spokane Chapter and is free and open to the public.
