2013 Map of Big Creek Peak

About this map

The Lemhi Range dominates this portion of the Idaho interior, where the high-elevation terrain is split between the Challis National Forest and Salmon National Forest. The landscape is defined by the significant peak of Big Creek Peak and the nearby Flatiron Mtn, serving as a drainage divide for numerous mountain streams. The watershed network is remarkably detailed, tracing the headwaters of Big Timber Creek and the various branches of the Big Creek system, including the North Fork and South Fork. Human presence is concentrated along the few access points like Big Creek Road and the Big Creek Campground. The map also captures the political geography of the region, specifically where the border between Lemhi and Custer counties traverses these remote ridges.
