About this map

Lemhi and the surrounding Lemhi Valley define this section of the high mountain corridor, where the Lemhi River serves as the primary geographic axis. The landscape is characterized by a network of drainage systems like Yearian Cr and Zeph Cr that flow from the steep elevations of Ramsey Mtn toward the valley floor. Transportation patterns are clearly visible through the alignment of Old Highway 28 and the more modern routing, while secondary routes like Lemhi Back Rd and Maiers Ln provide access to the dispersed valley homesteads.

The inclusion of the Lemhi River Salmon Trap near the northern boundary highlights the river's ecological significance and the historical management of its fisheries. To the west, the boundary of the Salmon National Forest marks the transition from the settled agricultural valley to protected mountain terrain. Topographic landmarks like Struggle Gulch and Berg-Green Gulch offer specific points of interest for those tracking local land use and geographic naming conventions in this part of Idaho.
