Hidden History: Dynamic Geology of the Gorge
June 13 @ 6:00 pm
Dynamic Geology of the Gorge with Scott Burns and Miranda Mendoza, Thursday, June 13, 6pm at The History Museum of Hood River County.
The Columbia Gorge is one of the most beautiful natural features of the United States. Dr. Burns will talk about the “Tale of Two Floods” that formed the Gorge. First, you had many flows of magma from eastern Oregon that formed the Columbia River Basalts which are stacked flows on top of one another. Then a second set of floods called the Ice Age Floods and the Missoula Floods came through the Gorge and carved it to what it is today, Thirdly, we have had many landslides form on the sides of the Gorge, with the most famous and most studied one, the Bridge of the Gods Landslide (officially called the Bonneville Landslide) which dammed the river 400 years ago. It was most likely triggered by a 7.0 earthquake on a fault across the river.
Dr. Scott Burns is a Professor Emeritus of Geology at Portland State University. He has been teaching for 54 years in places like Switzerland, New Zealand, Colorado, and Louisiana before coming back to where he was raised, Oregon, in 1990. He loves talking about the geology of Oregon. He has three degrees from Stanford University and the University of Colorado.
