About this map

The Continental Divide serves as the high-altitude backbone of this 1987 survey, marking the intersection of Salmon National Forest and Beaverhead National Forest along the Idaho-Montana border. The landscape is defined by its drainage systems and mining activity, notably an Open Pit Mine and several Prospects situated in the western portion of the sheet. These sites, located near Clear Creek and Poison Creek, indicate a history of resource extraction in this high-elevation terrain.

Water features are abundant despite the altitude, with Morrison Lake tucked below the divide near Lake Gulch. To the north, Baldy Mountain overlooks a series of deep drainages including Long Canyon and Wheeler Creek. In the south, the topography descends into Chamberlain Canyon and along the course of Horsethief Creek. The map records a sparsely developed wilderness where only primitive routes like Tenmile and Powderhorn Gulch provide access to the remote mineral claims and forest interiors.
