Hot springs rise beside the Bighorn River at the mouth of Wind River Canyon. As their mineral-rich waters cool, they leave deposits of pale travertine that form terraces beside the river. Shoshone, Crow and Arapaho people knew the springs as a place where visitors from different peoples could come in peace. The fur trapper Daniel Potts described the waters in a letter in 1826, adding an early written account to their much longer history.
