| Field Trip Description: The Kirk Bryan field trip of the Quaternary Geology and Geomorphology Division. A trip to classic locations in the Columbia River Gorge, where Lewis & Clark, James Dwight Dana, John Strong Newberry, Clarence Dutton, G.K. Gilbert, and J Harlen Bretz paved the way for discovery of some of Earth’s largest floods, lava flows, and landslides. We’ll visit sites of past and current research, including work on the 15 ka Missoula Floods, the 550 ya BP river-blocking Bridge of the Gods landslide, and November 2006 debris flows from Mount Hood—all while in a tremendous gorge cut through an active volcanic arc. |
