1950 Map of Monument Ridge

About this map

Vigilante Experimental Range and the Beaverhead National Forest dominate this mid-century high-country landscape, where the Gravelly Range and Monument Ridge divide the waters of the upper Missouri River Basin. The area is defined by its seasonal grazing and forest management infrastructure, rather than permanent towns. Clusters of activity are found at Cottonwood Camp, Three Forks Cow Camp, and Williams Camp, which served as hubs for livestock and timber operations. A solitary Mine located in the western foothills suggests the region's mineral interests.
