2013 Map of Borah Peak

About this map

Borah Peak, the highest point in Idaho, dominates this survey of the high-elevation wilderness within the Challis National Forest. Situated in the heart of the Lost River Range, the map details a stark alpine environment defined by steep drainage networks and significant mountain passes. High-country routes like Doublespring Pass Rd and Birch Springs Rd provide the primary access to this landscape of summits and canyons. The drainage pattern is led by the Pahsimeroi Mountains in the north, feeding into Doublespring Cr, while the southern reaches are marked by the headwaters of Rock Cr and Birch Springs. This map reveals the topographic complexity of the central Idaho interior, documenting remote landmarks such as Cayuse Canyon and Horseheaven Pass that are critical for navigating this high-altitude terrain.
