Chocolate Glacier is located on east slopes of
Glacier Peak in the
U.S. state of
Washington.
The glacier descends from to and is partially connected to
Cool Glacier which lies to its south just below the summit of Glacier Peak. As is true with all the glaciers found on Glacier Peak, Chocolate Glacier is retreating. Chocolate Glacier retreated approximately between 1906 and 1946, however during a cooler and wetter period from about 1950 to 1979, the glacier advanced . Chocolate Glacier has resumed retreating since and has given back , nearing its previously recorded minimal length. The current terminus at 1800 m is still the lowest of the east side glacier. Chocolate Glacier remains heavily crevassed and active to 1900 m. The lowest 300 m of the glacier are stagnant.
The Chocolate Glacier was given its name in 1906 by mountaineer
Claude Ewing Rusk, who commented on the chocolate colored water flowing from the glacier terminus.
