About this map

Salmon National Forest defines the high-altitude landscape of Lemhi County, Idaho, during the early 1950s. This survey reveals an era of transition for the local mining economy, specifically focused around the Blackbird Mine and several inactive sites such as the Sunshine Mine, Cobalt Mine, and Musgrove Mine. These operations, clustered along the steep drainages of Blackbird Cr and Panther Creek, highlight the region's historical reliance on mineral extraction.

The map records isolated human settlements and government infrastructure, including the Miller Ranch and Degan Ranch alongside the Copper Creek Ranger Sta. High-point fire detection is established at several peaks, including Blackbird Mtn Lookout, Gant Mtn Lookout, and Red Rock Pk Lookout. The drainage patterns of Big Deer Creek and Yellowjacket Creek illustrate the difficult terrain that dictated the placement of early roads and trails connecting these remote outposts and mining claims.
