ICE AGE FLOODS — Bruce Bjornstad, geologist and co-author of On the Trail of the Ice Age Floods, will present a free lecture Thursday, Nov. 14, entitled “Ice Age Floods and Long-Term  Recharge from Glacial Lake Columbia.” 
 
The program will start at 7 p.m. at the Eastern Washington University Science Building, Room 137, in Cheney sponsored by Ice Age Floods Institute Cheney-Spokane Chapter and the EWU Department of Geology.  Parking is available along Washington Street.
 
Lake Missoula was not the only source for Ice Age floods. At least one flood from Lake Columbia went down the Grand Coulee several hundred years after the last Missoula flood. Not long after this a final Lake Columbia flood went down the Columbia Valley from the breakup of the Okanogan Lobe. Before Grand Coulee was breached Lake Columbia recharged the Columbia River basalts for thousands of years, but ended 13-14 thousand years ago with the draining of Lake Columbia. Therefore, Lake Columbia does not get as much credit as it deserves.
