1969 Map of Lone Rock

About this map

Carson Sink (Depression) dominates this desert landscape, characterized by its wide Alkali Flat and shifting Sand Dunes. The survey, field-checked in 1969, reveals a stark terrain where natural geographic features meet mid-century military utility. In the southern reaches of the quadrangle, a prominent Navy Bombing Target Area is established, centered around the distinctive landmark of Lone Rock. This area is accessed by a rudimentary Jeep Trail, illustrating the remote and specialized use of the Churchill County desert during the Cold War era. The map provides a precise record of the basin's topography, capturing the intersection of the natural sink with federal defense installations before later environmental or administrative changes.
