[3] Chocolate Glacier retreated approximately 1,380 m (4,530 ft) between 1906 and 1946, however during a cooler and wetter period from about 1950 to 1979, the glacier advanced 450 m (1,480 ft).

Chocolate Glacier has resumed retreating since and has given back 350 m (1,150 ft), nearing its previously recorded minimal length.

[4] The current terminus at 1800 m is still the lowest of the east side glacier.

[5] 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.
