About this map

The Luke Air Force Range dominates this desert landscape in southern Arizona, representing a significant military training corridor during the mid-1980s. The terrain is defined by the sharp elevations of the White Hills and the Sauceda Mountains, which are separated by the namesake Black Gap. These landforms dictate the local drainage, specifically through the Sauceda Wash that cuts through the northeastern corner of the quadrangle.

Evidence of human infrastructure in this remote area is sparse but purposeful, including a singular Well and a prominent Trans Line cutting across the basin floor. The presence of Blindman Butte serves as a distinct navigational landmark within the military range. This survey, compiled from 1979 photography and field-checked in 1980, captures the area before modern changes, preserving the topographic character of this high-desert tactical environment.
