The high-elevation landscape of the Pioneer Mountains defines this portion of the Beaverhead National Forest, where the small settlement of Polaris sits at the northern edge of the Grasshopper Valley. This terrain is characterized by dramatic shifts in elevation, rising from the valley floor to prominent peaks like Baldy Mtn and Black Mtn. The hydrology of the area is a complex network of seasonal and perennial flows, including Grasshopper Creek and Billings Creek, alongside unique water sources like Old Faithful Spring and Lockridge Spring.
