1957 Map of Challis

About this map

The Salmon River and its multiple forks carve through this expansive section of central Idaho, anchoring a landscape defined by isolated mining camps and high-altitude settlements. In the mid-1950s, the region's mineral economy is visible through sites like the Blackbird Mine near Cobalt and the Sunbeam Mine along the Yankee Fork. These operations, alongside remote outposts such as Stibnite and Yellow Pine, highlight the enduring importance of extraction in the Salmon River Mountains.
