About this map

The Continental Divide zigzags through this high-altitude landscape, separating the headwaters of the Little Wind River from the sprawling lake basins of the west. Surveyed in the late 1930s, the map documents a remote alpine wilderness where the Bridger National Forest meets the Shoshone National Forest. This territory is defined by its massive granite peaks, including the prominent Mt Bonneville, Mt Geikie, and Mt Washakie.

Human presence is sparse, marked primarily by administrative and backcountry outposts. The South Fork Guard Sta and the John Day Cabin serve as lone landmarks for travelers navigating the extensive network of trails that connect these peaks. The hydrography is notably dense, featuring dozens of named alpine bodies such as Middle Fork Lake, Lake Kagevah, and Grave Lake, alongside the rushing waters of Milky Creek and the South Fork. The map preserves the geography of the Wind River Range before modern recreational pressures, showing the original surveyor's paths and established mountain passes like Washakie Pass.
