About this map

Lemhi River valley life in the early 21st century centers on the narrow corridor of Lemhi Rd where the small settlement of Lemhi and the nearby Lemhi Valley reside. The landscape is defined by the sharp contrast between the irrigated valley floor and the high, arid peaks of the Salmon National Forest. Tributaries like Yearian Cr and Reese Cr feed into the main river from deeply carved canyons and named landforms such as Ramsey Mtn.

Tracing the secondary roads reveals a network of ranching and land management access, including Maier's Ln and D C Bar Rd. Several distinct topographic features, such as Struggle Gulch, D C Gulch, and Berg-Green Gulch, punctuate the hillsides. The map reflects a modern era of land use where historic family ranch names and geographic descriptors persist alongside protected national forest boundaries.
