1938 Map of Borah Peak

About this map

Borah Peak and the high elevations of the Lost River Range dominate this 1930s landscape, providing a detailed look at the cattle ranching and early forest management infrastructure in Custer County. The map documents the high-altitude settlement pattern where family-run operations like Swauger Ranch, Carlson Ranch, and Jarvis Ranch are situated near vital water sources such as Thousand Springs and the Pahsimeroi River. This era shows a network of remote outposts, including the Pahsimeroi Ranger Station and Mahogany Ranger Station, which were essential for managing the surrounding national forest lands.
