1930 Map of Casto

About this map

Mining operations and remote homesteads define this high-altitude landscape of central Idaho during the mid-1920s survey period. High peaks such as Middle Fork Peak and Sleeping Deer Mtn tower over a complex network of drainages including Pistol Creek and the Salmon River. The map meticulously records the industrial footprint of the era, from the Yellowjacket Mine in the northeast to the Lost Packer Mine and Parker Mill further south. These sites, often located at extreme elevations near Pinyon Peak, were the lifeblood of the local economy before the large-scale consolidation of national forests.
