Volcanoes, Landslides, and Angry Gods—A Pacific Northwest Connection

View of headscarp of Red Bluffs landslide (adjacent to the Bonneville landslide), looking northwest and showing the bedded volcaniclastic sediments (gray layers) that are dipping about 7 degrees toward the viewer and in which sliding has occurred. The slightly darker gray and orange-brown unit in the top quarter of the scarp face is Columbia River Basalt. The slowly creeping Crescent Lake landslide, on which the photographer is standing, is a reactivated part of the Red Bluffs landslide. USGS photo by T. Pierson.
