1930 Map of Casto

USGS Topo · Published 1944

About this map

Mining operations and isolated mountain ranches define this central Idaho landscape in the late 1920s. The convergence of four different national forests—Salmon, Challis, Payette, and Idaho—demonstrates the vast wilderness management of the era. Settlement is sparse, appearing primarily as family-named outposts such as Falconberry Ranch, Ramey Ranch, and Boyle Ranch, often situated near life-sustaining water sources like Warm Spring Creek or the Middle Fork.
