About this map

The Continental Divide serves as the dramatic southern boundary of this 1950 survey, tracing the high ridges between Beaverhead National Forest in Montana and Targhee National Forest in Idaho. At the heart of the Centennial Valley, the Red Rock Lakes National Wildlife Refuge encompasses the sprawling waters of Lower Red Rock Lake. The landscape is a mix of high-altitude wetlands and steep timbered slopes, supporting an economy of isolated homesteads and livestock operations.

Evidence of early 20th-century life is scattered throughout the valley, from the Doyle School and a small Cem to several established family operations like the 7 L Ranch, Goble Ranch, and Staudenmeyer Ranch. Near the southern peaks, a Coal Mine and the Little Creek Trail suggest the area's extraction and navigation history. The Red Rock River meanders through the flats, passing by the Brundage Bridge and Refuge Headquarters near Lakeview.
