About this map

Centennial Valley serves as a high-altitude sanctuary on this 1950s survey, dominated by the expansive Lower Red Rock Lake and the Red Rock Lakes National Wildlife Refuge. The map details the early mid-century infrastructure of the Lakeview settlement, including the Observation Tower Refuge Headquarters and a nearby Cem. Ranching heritage is prominent throughout the basin, with the Goble Ranch, Staudenmeyer Ranch, and 7 L Ranch established along the tributaries.

South of the valley, the Centennial Mountains rise sharply toward the Continental Divide, which forms the border between Montana and Idaho. This rugged southern section reveals local education and industry history via the Doyle School and an Inactive Coal Mine tucked into the canyons. Notable high points like Baldy Mountain and Patchtop Mountain overlook a complex network of pack trails and forest boundaries within the Beaverhead National Forest.
