1990 Map of Malpais Hill

About this map

The Crater Range dominates the southern landscape of this Arizona survey, its jagged topography rising sharply above the desert floor. This 1990 provisional map documents a portion of the Barry M Goldwater Air Force Range, an area largely defined by its military boundaries and natural obstacles. The northern section is marked by the distinct prominence of Malpais Hill, a volcanic landmark standing isolated amidst the broad drainage patterns of the Midway Wash. The map reflects a landscape managed for defense purposes, where human presence is restricted to military use and the natural geography remains largely undisturbed. It provides a technical look at the intersection of steep mountain terrain and the expansive alluvial plains typical of the Maricopa County desert interior.
