View of northeast side of Mount Rainier (right) and Little Tahoma Peak (left
center). Note large embayment, now partly filled by the snowclad summit crater,
which yielded the sector collapse that formed the Osceola Mudflow. The flow
diverged across Steamboat Prow, the apex of the 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 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 avanache originating from Little Tahoma
Peak.
