1956 Map of Twin Peaks

USGS Topo · Published 1960

About this map

Twin Peaks and the high ridges of the Challis National Forest dominate this mid-century survey along the Custer and Lemhi county line. The landscape is defined by its water resources and high-altitude lookouts, notably the White Goat Lookout which oversees a network of alpine basins including White Goat Lake and West Fork Lakes. To the south, the Mosquito Flat Reservoir and Slab Barn Lake indicate the managed hydrology of the era, supporting the lower drainages of Challis Creek and Garden Creek. Evidence of mid-century exploration is found in the scattered prospects near Big Hill Gulch and the isolated Gaging Sta along Challis Creek, while landmarks like Camas Meadows and Corkscrew Mtn provide distinct navigational points for backcountry travel.
