About this map

Lemhi River valley life in the early 21st century is defined by the narrow corridor of riparian land between the high mountain ranges of east-central Idaho. The settlement of Lemhi serves as the focal point for this rural landscape, where the Lemhi Rd and Old Hwy 28 trace the historical movement of goods and people through the high desert. The terrain is marked by numerous drainages such as Yearian Cr, Reese Cr, and Mill Cr that feed into the main river channel from the surrounding peaks.

Evidence of local land use is preserved in names like D C Bar Rd, OC Bar Rd, and Lee Creek Ln, reflecting ranching and family-held tracts. To the southwest, the boundary of the Salmon National Forest signals a shift from valley agriculture to protected federal highlands. This survey documents the complex topography of the Bitterroot foothills, including the distinctively named Struggle Gulch and Berg-Green Gulch, showing how the modern road network adapts to the steep gradients of the Idaho backcountry.
