About this map

The Nevada Test Site dominates the western portion of this 1961 survey, revealing a landscape defined by Atomic Energy Commission activity and Cold War defense operations. Military boundaries carve through the high desert, separating Area 9 and Area 10 from the vast Nellis Air Force Range. Infrastructure supporting these restricted zones is visible via the Groom Lake Road and an Underground Telephone Line that cuts across the northern basin toward the Emigrant Valley.

Topographic details focus on the stark ridges of the Half Pint Range, including named landmarks like Jangle Ridge, Banded Mtn, and the distinctive Cockeyed Ridge. The eastern edge of the map transitions into the Desert National Wildlife Range, where the terrain drops away from Groom Pass into the open valley. Networked Jeep Trails and a labeled abandoned route hint at the early exploration and logistical movements required in this high-security Nevada interior.
