About this map

The Salmon National Forest dominates this section of Lemhi County, where the high ridges of the Lemhi Range descend toward the river valley. The Salmon River flows through the western edge of the area, a critical water source that shaped early settlement and transit. Evidence of the region’s ranching and livestock history is preserved at Mckim Stock, situated near the confluence of Mckim Creek and its various tributaries.

Transportation routes trace the narrow drainages and canyon floors, including the Old Stage Rd and Allison Creek Rd, which provide access to the interior highlands. These roads follow the same paths used for generations to move cattle and supplies between the mountain grazing lands and the valley. Notable topographical features like Long Ridge and the sharply cut Dry Gulch define the landscape between the N Fork Mckim Cr and Phantom Cr.
