1950 Map of Upper Red Rock Lake

About this map

The Red Rock Lakes National Wildlife Refuge anchors this high-altitude landscape, protecting the waters of Upper Red Rock Lake and Swan Lake. The terrain is defined by the Continental Divide, which separates the high peaks of the Centennial Mountains from the Centennial Valley. This mid-century survey captures a ranching and early tourism economy, evidenced by several family-named operations such as Edwards Ranch and Cook Sheep Ranch, alongside the Selby Resort on the shores of Elk Lake. In the high timber of the Beaverhead National Forest, traces of resource extraction appear at the Lost Mine near Lost Mine Bench. The map illustrates a complex network of mountain passes, including Red Rock Pass and Snowshoe Pass, which served as vital connectors between the valley floor and the surrounding basins.
