About this map

Lemhi Range terrain dominates this high-elevation mountain landscape, where the Salmon National Forest meets the Challis National Forest. The map is centered on Big Creek Peak and the nearby Flatiron Mtn, revealing a network of vital waterways including the N Fork Big Creek and the combined S Fork Big Creek-Iron Cr. These drainages historically guided travel and early resource access through the steep slopes of the Salmon River mountains.

The boundary between Lemhi and Custer Counties bisects the topography, following the ridgeline and intersecting with Big Creek Rd. A small system of trails and unpaved routes, such as the Flatiron Mountain Loop, provides access to the high basins fed by Big Timber Creek and Prospect Cr. This survey documents a largely undeveloped wilderness characterized by its complex hydrography, from the headwaters of Ditch Cr to the reaches of Bear Cr and Hillside Cr.
