About this map

Sawtooth National Forest encompasses the northern half of this Idaho landscape, dominated by the peaks and drainages of the Sublett Range. The topography is defined by narrow canyons and reliable water sources, including Sublett Reservoir and its namesake Sublett Cr, which transitions into Lake Fork as it flows toward the forest boundary. Natural springs such as Pine Grove Spring and South Fork Fall Creek Spring are vital markers in this high-elevation environment, where water flow determines the placement of roads and access points.

Road systems like Sublett Rd and 1800 S Rd navigate the lower elevations, while seasonal routes like the Lake Fork Loop (Snow) and Cold Springs Canyon Loop (Snow) indicate the winter character of the terrain. The border between Cassia and Power counties cuts through the northeast, following the height of land near Ward Canyon. Notable landmarks including Beaver Dam Canyon and Hutchey Canyon provide clear geographic reference points for researchers studying land use or family grazing allotments in the region.
