1938 Map of Mount Bonneville

About this map

The Continental Divide zigzags through this high-altitude landscape of the Wind River Range, where surveyors T. F. Murphy and S. C. Kain documented the glaciated terrain in the late 1930s. Centered on the massive granite peak of Mt Bonneville, the map reveals a wilderness accessible only by a network of high-country paths, labeled simply as Trail. Human presence is sparse and utilitarian, represented by seasonal outposts like the South Fork Guard Sta, the John Day Cabin, and a Cow Camp. The drainage patterns of the Shoshone National Forest are defined by hundreds of alpine water bodies, including the expansive Middle Fork Lake and the clustered Milky Lakes. Key mountain crossings such as Hailey Pass and Washakie Pass provide the only navigable breaks through the high ridges, connecting the Fremont and Sublette county line.
