2020 Map of Morrison Lake

About this map

The Continental Divide National Scenic Trail winds through the high elevations of the Beaverhead Mountains, tracing the border between the Salmon National Forest in Idaho and the Beaverhead National Forest in Montana. This high-country landscape is defined by its drainages, where Morrison Lake sits at the head of Lake Gulch. To the south, the topography is carved by Horsethief Canyon and Poison Cr, while the western slopes fall away into Powderhorn Gulch. The Continental Divide itself serves as the primary surveyor's benchmark, splitting the waters that flow toward the Pacific and the Atlantic. This area remains largely defined by its natural hydrology and forest boundaries, with significant peaks like Baldy Mtn overseeing a network of creeks including Tenmile Cr and Simpson Cr.
