2024 Map of Big Hole Pass

About this map

Big Hole Pass sits at the high-elevation boundary between Idaho and Montana, serving as a critical crossing point between the Salmon National Forest and Beaverhead National Forest. This modern 2024 survey documents the complex watershed system of the Bitterroot Mountain range, where headwaters like Nez Perce Creek flow west while Ruby Creek drains toward the east. The map captures the current course of the Continental Divide National Scenic Trl as it traces the ridge through the Continental Divide. Land access is shown through forest roads such as Gibbonsville Rd and Dahlonega Creek Rd, illustrating the intersection of recreation and resource management in this high-altitude landscape. Notable peaks like Morgan Mtn and Three Mile Ridge Tri anchor the topography, providing a detailed view of the terrain that has historically separated Lemhi and Beaverhead counties.
