Join MNHC and the Glacial Lake Missoula Chapter of the Ice Age Floods Institute for the grand opening of our newest exhibit! Learn more about the Ice Age lake and the massive flood event that carved out the Columbia River Gorge and created unique landscape features from the Missoula Valley to the Pacific Ocean.

At 5:00, GLM Chapter President Jim Shelden will share stories of Joseph Pardee, the geologist whose evidence of Glacial Lake Missoula helped support J. Harlen Bretz’s outrageous and controversial theory of a cataclysmic flood event.

Thank you to the Montana Department of Tourism for the grant award to bring this new exhibit to life.
