Brent Cunderla, geologist at the Bureau of Land Management, discussed the history and effects of the ice age glaciation and floods. In 2009 the Ice Age Floods National Geologic Trail was created. The trail follows the routes of floods during the ice age. Brent showed great maps and pictures of lava flows, glaciers, and flood routes that carved out much of the central Washington landscape. A one point a 30-mile wide ice dam blocked glacial Lake Missoula for miles to the depth of 2000 feet. When the dam broke, the water was emptied over a few days and flooded north central Washington and washed soil miles south and formed our "scab-lands", coulees, and dry falls.For more information, check out www.iafi.org (Ice Age Floods Institute).
