THE LAND -- The Cheney-Spokane Chapter of the Ice Age Floods Institute is sponsoring a free public lecture “Latest Pleistocene Geologic History of Upper Grand Coulee” by Dr. Patrick Spencer on Thursday, (Nov.17), 7 p.m., on the Eastern Washington University, Cheney Campus, in Science Building, Room 137.

Dr. Spencer,  professor of geology, Whitman College will lecture on 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.
