Ice Age Floods – Giant Current Ripples

Check out this 2-Minute Geology expedition with Nick Zentner and Tom Foster exploring the Giant Current Ripples at West Bar and Camas Prairie. Ice age floodwater 650 feet deep – moving at 65 miles per hour – left Giant Current Ripples along the Columbia River at West Bar! The ripples at West Bar are 20 feet high, spaced up to 100 yards apart. Giant Current Ripples at Camas Prairie, Montana are also described. The Montana ripples helped Joseph Pardee understand that Glacial Lake Missoula had emptied suddenly. Learn more about Glacial Lake Missoula, Lake Bonneville and the Ice Age Floods at
