[3] Much of it becomes the source of Adams Creek, a tributary of the Cispus River.

Between 11,800 and 9,200 feet (3,600 and 2,800 m), the glacier flows through a steep icefall that provides challenging climbing through a maze of seracs.

The first ascent of the glacier was by Fred Beckey, Dave Lind, and Robert Mulhall in July 1945.

[4] Below 8,400 feet (2,600 m), the glacier spreads into a broad sheet with five separate tongues of ice extending out to termini between large moraines.

On its easternmost tongue, it ends at a glacial tarn, or small ice-choked lake above High Camp.
