Hanging Lake is a unique example within the Southern Rocky Mountains biophysiographic province of a lake formed by travertine deposition. It is one of the larger and least altered travertine systems in the province, where natural geologic and hydrologic processes continue to operate as they have done throughout the history of the lake. The site also supports one of the best and largest examples of a hanging garden plant community in the province.
