About this map

The high-desert terrain of Nye County, Nevada, is documented here in a survey conducted in cooperation with the Atomic Energy Commission. The landscape is dominated by the Pancake Range, which divides the expansive Big Sand Springs Valley to the west from the Railroad Valley to the east. At the center of the range, Portuguese Mtn rises above Wood Canyon, while the southern reaches features volcanic activity evidenced by Lava flows and the distinctive Black Rock Summit.

Settlement is sparse and centered around vital water sources, such as Lockes and the Etcheverria Well. The reliance on these springs is clear, with numerous named points like Martin Spring and Reynolds Springs dotting the map. This era in the late 1960s shows a network of Jeep Trails and the Ike Trail connecting remote Prospects and borrow pits, reflecting the ongoing geological exploration and ranching history of this Great Basin environment.
