The Great Missoula Floods

July 8, 2014

Rick Thompson, President of the Ice Age Floods Institute, will speak on how the floods forever changed the landscape of the Pacific Northwest. He will be at St. John Library on July 8 at noon; and later at 7 p.m. at the Colfax Library. On July 9, he will be at the Tekoa Library at noon. Mr. Thompson’s illustrated presentation explains how multiple glacial Lake Missoula floods propelled over 500 cubic miles of water, ice, rock and mud from northwestern Montana to the Willamette Valley of Oregon. The July 8 presentations aim to help all ages understand how this glacial activity effected the Northwest; while the July 9 presentation delves more deeply into glacial erratics, the giant boulders that dot our landscape after ancient glaciers receded.
