2013 Map of East of May

About this map

The Lemhi Range dominates the northeastern landscape of this Idaho study, where the high elevations of the Challis National Forest give way to the broad Pahsimeroi Valley. This drainage basin is defined by the Pahsimeroi River and its various tributaries, including Patterson Cr, Morse Cr, and Falls Cr. The map captures a transitional zone between mountain wilderness and the valley floor, where the county line between Lemhi and Custer counties follows the natural watercourse. A network of rural routes and trails, such as Pahsimeroi Rd and Furey Ln, illustrates the reach of ranching and remote access into the foothills. The presence of Tater Cr and Mahogany Cr further highlights the numerous drainages that sustain the valley's ecosystem below the peaks of the Challis wilderness.
