About this map

Lemhi Valley and the surrounding high-altitude drainage systems define this section of the Salmon National Forest. The landscape is dominated by the Lemhi River corridor, which serves as the primary axis for local ranching and transit via Lemhi Rd. Tributaries such as Big Eightmile Cr and Milk Cr descend from the upland basins, reflecting a land-use pattern focused on water rights and livestock grazing.

Topographic features like Mineral Hill and Mollie Gulch suggest a history of resource extraction and prospecting. The map's extensive network of secondary roads and forest access points, including Lee Creek Rd and Nat For Dev Rd 105, indicates the importance of timber and recreation management in this part of Lemhi County. The transition from the valley floor to the high-relief terrain of Swan Basin provides a clear view of the geographic constraints on settlement in the northern Rockies during the early twenty-first century.
