1968 Map of Black Rock Summit

About this map

The Pancake Range dominates this late-1960s landscape, providing a high-elevation divide between the broad Big Sand Springs Valley and the more confined Big Round Valley. This survey, conducted in cooperation with the Atomic Energy Commission, captures the region's volcanic character, notably at Black Rock Summit and the dramatic escarpment known as The Wall. The presence of a Lava field and a Cinder Pit reflects the local geologic history, while scattered Prospects suggest the era's ongoing mineral exploration. Human infrastructure remains sparse in this arid terrain, focused primarily on essential resource points like Black Rock Spring and a remote Radio Tower, all interconnected by a network of Jeep Trails.
