About this map

The Kofa National Wildlife Refuge and the Yuma Proving Ground meet in this 1980s landscape, defined by a stark boundary between environmental conservation and military operations. The rugged terrain is anchored by the Castle Dome Mountains to the west and the Black Hills near the center, separated by the arid expanses of Hogg Valley and King Valley. Remote four-wheel-drive tracks serve as the primary infrastructure through these basins, reflecting a landscape used for both wilderness preservation and defense testing.

Signs of mineral exploration are scattered throughout the mountain slopes, documented by labels for a Mine Shaft, a Prospect, and several Gravel Pit locations. Landmarks like Miracle and various Tower sites punctuate the valley floors. This survey captures a specific era of Arizona desert management before modern expansion, where industrial extraction and military utility shared the land with protected wildlife habitats.
