About this map

Antelope Flat defines the central topography of this Custer County landscape, situated between high ridges and drainage networks that feed into the Salmon River basin. In the early 1960s, this area was characterized by a remote network of unpaved routes, including a prominent Jeep Trail and various hiking paths that navigated the steep elevation changes. To the northeast, the Challis National Forest boundary marks the transition into more densely timbered terrain.

Water sources are vital markers in this arid environment, with Warm Spring and Summit Spring providing essential points of interest for early land use. The map captures the erosion patterns of Grand View Canyon and the course of high-altitude streams like Broken Wagon Creek and Gooseberry Creek. A single Gravel Pit along the main road suggests the localized extraction of materials used for maintaining the area's infrastructure during this era.
