Mining and ranching activity define this mid-century survey of the high Salmon River country. The local economy is anchored by the Blackbird Mine and the settlement of Cobalt in the southern portion of the map, alongside several non-operational sites like the Sunshine Mine and Cobalt Mine. These industrial nodes are set against a landscape of high ridges, including Trapper Ridge and Little Deer Creek Ridge, where small clearings like Fritzer Flat and Trapper Flat provided level ground amidst the steep drainage basins.
