The Salmon National Forest defines this high-altitude landscape in the Salmon River Mountains, where the Salmon Wild and Scenic River carves through the northern boundary. This modern survey illustrates the complex drainage network and rugged geography typical of Lemhi County, centered on landmarks like Napoleon Hill and Napoleon Ridge. The map reveals a history of backcountry access through a series of Forest Service developments, including Nat For Dev Rd 046 and the Ridge Road Napoleon.
