2014 Map of Bannock Pass

About this map

The Continental Divide serves as the spine of this landscape, marking the high-altitude boundary between the Beaverhead National Forest in Montana and the Salmon National Forest in Idaho. At this rugged intersection of Beaverhead and Lemhi Counties, Bannock Pass provides a transition through the mountain range. The terrain is defined by a series of steep drainages including Black Canyon, Jakes Canyon, and Railroad Canyon, while numerous water sources like Wagonbox Spring, Boche Spring, and Irish Bay Springs dot the slopes. A network of forest roads and trails, such as Railroad Canyon Rd and S Divide Creek Rd, navigates the complex topography near Grizzly Hill. This map documents a largely undeveloped wilderness where the primary human footprint is found in the naming of remote gulches and the infrastructure of the National Forest system.
