Timpanogos Glacier is a buried glacier that is located in the Wasatch Range, Wasatch-Cache National Forest, and is the last glacier in the U.S. state of Utah. The glacier is situated on the north slope of Mount Timpanogos (11,749 feet (3,581 m)). During the dust bowl drought of the 1930s, the above-ground portion of the glacier was reduced to a permanent snowfield. The glacier is now considered to be a rock glacier, since the remaining ice is now buried in the talus. In 1994, the rocks parted, revealing a crevasse in the buried glacier. One witness described it as being "40 feet thick at least" Emerald Lake is a small proglacial lake which lies at the terminal moraine left behind by the now mostly vanished Timpanogos Glacier.
