The Continental Divide serves as a natural and political boundary in this high-altitude landscape, separating Beaverhead County, Montana from Clark County, Idaho. The terrain is defined by the Centennial Mountains, where the Continental Divide National Scenic Trl traverses rugged ridgelines through the Targhee National Forest. To the north, the elevation drops into the Centennial Valley, much of which is protected by the Red Rock Lakes National Wildlife Refuge.
