A wonderland of travertine terraces and crystal springs



At the base of the rolling Aspen Mountains, less than five miles outside of Soda Springs, this 195-acre preserve supports a series of remarkable geological formations surrounding magnificent terraced mineral pools.

It is a refuge for waterfowl, deer, elk and several rare plant communities. Birding is consistently good and nature trails get visitors up close to both the geologic formations and abundant wildlife.
