1969 Map of Lone Rock SW

About this map

The Carson Sink Alkali Flat (Depression) dominates this high-desert landscape, reflecting the stark geography of Churchill County as it appeared in the late 1960s. This terminal drainage basin is defined by its extreme isolation and lack of traditional landmarks, serving as a catchment for the region's intermittent waters. In the northeastern portion of the sheet, the presence of the Navy Bombing Area indicates the specialized military utility found for these remote, arid reaches. Scattered Sand Dunes are the only significant relief in an otherwise flat expanse. Mapped by the Geological Survey using aerial photography from 1968, the map illustrates a landscape nearly devoid of permanent human infrastructure or roads, preserved here as a study in Great Basin geology and mid-century military land use.
