2020 Map of Borah Peak

About this map

Borah Peak dominates the southern landscape of this 2020 survey, marking the highest elevation in the state within the Challis National Forest. The map documents the high-altitude terrain of the Lost River Range and the Pahsimeroi Mountains to the north, connected by the high transit point at Doublespring Pass. The drainage patterns are defined by numerous seasonal and perennial flows, including Doublespring Cr and Rock Creek, which cut through the steep topography. Human presence is largely limited to the Forest Service road network, such as Doublespring Pass Rd and Birch Springs Rd. Significant watering points like Freighter Spring, Mule Spring, and Birch Springs indicate the essential water sources for pack animals and wildlife in this high-desert mountain environment. This record provides a clear view of the wilderness character and geological formations, from the depths of Cayuse Canyon to the summits above the tree line.
