About this map

Nellis Air Force Range dominates this corner of Nye County, where military operations and wild horse conservation overlap in a high desert environment. The terrain is defined by the stark transition between the broad floor of Monotony Valley and the jagged heights of the Belted Range. An Inactive Target and a Restricted Access Area reflect the mid-century expansion of government land use for defense testing.

Mineral history is present in the northeastern corner, where the Oswald Mine and several prospect pits sit on the valley’s edge. The western half of the map is largely dedicated to the Wild Horse Management Area, covering significant elevations such as Gray Top Mountain and the steep slopes of Ragged Ridge. Connectivity across this landscape is limited to specialized points like White Saddle Pass, illustrating the isolation of these basin-and-range formations in the late twentieth century.
