About this map

Kofa National Wildlife Refuge and the extensive Yuma Proving Ground dominate this 1980s landscape, illustrating the intersection of conservation and military activity in the Arizona desert. The map captures a region defined by arid basins and prominent peaks, including Courthouse Mountain and Polaris Mountain. To the south, the Gila River winds through the Hyder Valley, providing a corridor for small settlements like Hyder and Montezuma.

Mining activity is a significant historical marker here, with several operations scattered throughout the ranges. Researchers can find the North Star Mine and Midas Mine in the northwest, while the Silver Prince Mine is situated further south. The drainage patterns are meticulously detailed through numerous washes, such as Alamo Wash and Hoodoo Wash, which reveal the hydrologic character of the Palomas Plain and Ranegras Plain.
