On Wednesday evening, May 16, 2007 at 7:00 PM at the Museum of the Oregon Territory in Oregon City, I heard the author, Ellen Morris Bishop, the accomplished geologist and photographer, explain the Ice Age Floods (there were several) through geologic time with a global climate change perspective. She is the author of “In Search of Ancient Oregon”, “Hiking Oregon’s Geology”, and “Best Hikes with Dogs: Oregon”. The event was sponsored by the Lower Columbia Floods Chapter (LCFC) of the Ice Age Floods Institute (IAFI) and the Clackamas Heritage Partners (CHP).
Besides the Missoula Floods of 18,000 to 13,000 years ago, she talked about the other great floods: the Bonneville about 18,500-15,000 years ago that went through Hells Canyon and along the Snake River; Altay Mountains, Siberian which may have been the Earth’s greatest floods; the Three Glaciers Flood—along the Arkansas River, Chaffee County, Colorado of 20,000 years ago; North Simpson Desert in Australia; and Glacial Lake Agassiz Floods (Hudsons Bay) of 8,200 years ago.
