Middle Fork Salmon River carves a deep path through this wilderness landscape where Valley, Custer, and Lemhi counties meet. The confluence of Loon Creek and the Salmon River serves as a focal point for backcountry travel, evidenced by the presence of the Lower Loon Creek Airport and the Lower Loon Creek Bridge. This 2017 survey reflects a terrain defined by its complex hydrography, from high-elevation waters like Falconberry Lake to geothermal features including Hospital Hot Spring and Cox Hot Springs.
