1991 Map of Francs Peak

About this map

Kirwin stands as a focal point of high-altitude mining history within the Shoshone National Forest. This 1991 revision detail's a landscape defined by the extraction of silver and copper, evidenced by a dense network of shafts and tunnels concentrated around the Galena Basin and Brown Basin. Significant sites including the Gold Reef Tunnel, Iowa Mine, and Mendota Mine are clustered near the headwaters of the Greybull River. The terrain is strictly regulated, with the Washakie Wilderness boundary cutting across the steep slopes of Francs Peak and Jojo Mountain. This document serves as a critical record of the region's late 20th-century state, showing the relationship between industrial mining footprints and the preserved wilderness, specifically where the Wind River RD terminates at the base of Greybull Pass.
