About this map

The Continental Divide defines this high-country landscape along the border of Montana and Idaho, marking the boundary between Beaverhead National Forest and Salmon National Forest. This 1960s survey, updated in the 1980s, captures the high-altitude headwaters of several drainage systems, including the complex forks of Maiden Creek and Horse Prairie Creek.

Evidence of early transit and land use is visible in the Old Railroad Grade winding through the western hills and the presence of the L-Diamond Ranch. Geographic points of interest like Deadman Pass and the remote Dad Creek Lake sit among steep canyons and ridges, including Rough Canyon and Elk Mountain. The map also documents an extensive system of water management with numerous labels for Ditch lines carved into the slopes to direct runoff.
