Glacial Lake Missoula was the source of much of the water for the famous Ice Age Floods of the Pacific Northwest. Featured field evidence for the lake include strandlines above Missoula, Montana, giant current ripples at Camas Prairie, and striking rhythmites along Interstate 90 at Nine Mile Road near Missoula.

Tom Foster (http://HUGEfloods.com) and Nick Zentner (Central Washington University) have been hiking together in Washington for years. This ’Glacial Lake Missoula’ episode stands alone, in addition to their popular ‘I-90 Rocks’ and ‘2 Minute Geology’ video series.
