2024 Map of Big Creek Peak

About this map

The Lemhi Range dominates this high-altitude landscape along the border of Lemhi and Custer counties. This 2024 survey captures the wilderness character of the region, where the Salmon National Forest meets the Challis National Forest. Notable peaks like Big Creek Peak and Flatiron Mtn anchor the terrain, providing the source for numerous drainages including the North Fork Big Creek and South Fork Big Creek. A sophisticated network of backcountry paths, such as the Big Timber Creek Trl and the Flatiron Mountain Loop Trl, demonstrates the area's contemporary role as a managed recreational and forest resource. The inclusion of Big Creek Rd and the South-Fork Big Creek-Iron Cr. Trl illustrates how modern access corridors still follow the primary watercourses through this high-desert mountain environment.
