1963 Map of Antelope Flat

About this map

Antelope Flat defines the central basin of this Custer County landscape, situated between high ridges and the winding drainage of Warm Spring Creek. Surveyed in the early 1960s, the map reveals a remote environment primarily characterized by its water sources and rugged transit corridors. Grand View Canyon cuts through the northern section, while a series of mountain streams including McGowan Creek, Gooseberry Creek, and Sheep Creek flow toward the valley floor. The eastern boundary is marked by the Challis National Forest line, indicating a transition from open flatlands to protected timberland. Human activity is sparse but evident through a network of Jeep Trails and a local Gravel Pit, reflecting the area's use for ranching, resource extraction, and high-desert navigation. The map also records several specific water points like Summit Spring, which were critical for travel and livestock in this arid high-elevation terrain.
