2017 Map of Spring Hill

About this map

Spring Hill and the dramatic peaks of the Lost River Range dominate this corner of Custer County within the Challis National Forest. The landscape transitions from high mountain slopes down into the Pahsimeroi Valley, where the Pahsimeroi River flows through the eastern portion of the survey. Significant watercourses including Doublespring Cr, Burnt Cr, and Goldburg Cr drain the surrounding heights, while Carlson Lake provides a notable point of interest on the western edge. Access through this backcountry is defined by primitive routes such as Donkey Hills Rd and Nat For Dev Rd 118. The map illustrates the complex interplay of high-altitude topography and the valley floor drainage systems that have long shaped the land use and accessibility in this part of Idaho.
