Mount Rainier rises above Yakima Park on the north side of the volcano in this 1972 photo. Emmons Glacier descends to the left from the summit within a broad valley alongside Little Tahoma Peak (far left). The valley formed when part of Mount Rainier collapsed during an eruption episode about 5,600 years ago, producing the Osceola mudflow that reached the Puget Sound area.
