Great Basin National Park Glaciers / Glacial Features

Great Basin National Park supports several rock glaciers and glacial features from past glaciation. The largest rock glacier can be found in in the Wheeler peak cirque. This glacier was first documented in the the Fifth Annual Report of the United States Geological Survey, 1883-1884. In the 1950's the cirque still contained an active glacier with an active front, neve, bergshrunds, crevasses, and a small moraine. It is unknown exactly when the conversion from active glacier to rock glacier occurred.
