Join the Ice Age Floods Institute for an informative lecture of the Five Great Lakes of the Missoula Floods. Chapter President Lloyd Stoess will review both Glacial Lake Missoula and Glacial Lake Columbia. Although both of these lakes formed for the same reason their history is very different. When the waters in Glacial Lake Missoula were catastrophically released, they entered the Columbia River drainage system. On their way to the Pacific Ocean, the floodwaters were restricted at three different locations forming three temporary lakes. This presentation will give an overview of all of these five great lakes and is a precursor to our fall bus tour that will be coming up on Oct. 7. Attend one or both, the choice is yours.
