1990 Map of West of Vopoki Ridge

About this map

The Barry M Goldwater Air Force Range dominates the northern and central portions of this borderlands survey, illustrating the significant military footprint in the Southwest during the late twentieth century. This arid landscape is defined by the Yuma Desert, which spans the international boundary between the United States of America and Mexico. South of the border, the terrain transitions into the Desierto de Altar in Sonora. The map details a sparse network of 4wd tracks that navigate the sandy expanses, providing the only access to remote installations like the Lookout Tower and Radio Tower Lookout Tower. This provisional edition serves as a precise record of international geography and military land use in Yuma County before the modern era of border security and increased desert navigation.
