Abstract
Several hundred years after the last flood from glacial lake Missoula, there was at least one last flood that occurred during the breakup of the Okanogan Ice Lobe. The Okanogan Lobe retreated northward from the Waterville Plateau at the end of the Ice Age about 14,000 years ago. That’s when an outburst flood—probably from the sudden breakup of the glacial Lake Columbia and restricted to the Columbia River valley, flowed west through the breached ice dam before turning south toward West Bar (dashed blue line).
