1996 Map of Bryan Mountains

About this map

The Bryan Mountains rise sharply between the desert floor of the San Cristobal Valley and the Mohawk Valley, defining a landscape of intense preservation and military utility. This 1996 survey illustrates the convergence of the Cabeza Prieta National Wildlife Refuge and the Cabeza Prieta Wilderness, showcasing the complex administrative boundaries that govern the southwestern Arizona desert. The map captures a moment when large swaths of the region were designated as the Barry M Goldwater Air Force Range, where access was restricted to facilitate defense operations within a fragile ecological corridor. The topographical detail reveals the isolated character of these peaks, which served as critical landmarks for travelers navigating the arid basins of the Yuma region.
