The steep headwall of the scarp created by collapse of St. Helens on 18 May 1980 towers 550 m above the crater floor. The white areas on the crater rim are glaciers that were truncated by the collapse. Steam rises at the right from the new crater in this August 1980 view. Mount Hood is visible in the distance to the south across the Columbia River.  Photo by Lee Siebert, 1980 (Smithsonian Institution).
