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.
