View southeast of Mount Rainier, August 1982. The northeast flank of the volcano (forming left skyline, including summit) collapsed catastrophically as a gigantic landslide (debris avalanche) and transformed into the gigantic Osceola mudflow (or "lahar") about 5800 years ago. The present summit and its craters were formed during an eruption about 2000 years ago.

Mount Rainier from the NE showing post-5,600-year-old lava cone and crater, buried edge of collapse crater (hachured lines) now partly filled by the snowclad summit crater, which yielded the sector collapse that formed the Osceola Mudflow. The flow diverged across Steamboak Prow, the apex of partly barren triangle of rock at the right side of the photograph, into the main fork of the White River (center), now the site of the Emmons Glacier, and northward into the West Fork White River (to right of photo). Dark rubble on surface of the lower part of the Emmons Glacier is from the 1963 debris avalanche originating from Little Tahoma Peak.
