1990 Map of Tule Mountains

About this map

The Camino Del Diablo, an ancient and treacherous route through the Sonoran Desert, dominates the northern half of this borderlands survey. This 1990 map captures the stark intersection of military administration and ecological preservation, where the Barry M Goldwater Air Force Range meets the Cabeza Prieta Wilderness and National Wildlife Refuge. The international boundary between the United States and Mexico cuts across the center, revealing the southern reaches of the Tule Mountains and the northern extent of the Sierra El Choclo Duro in Sonora. Essential water sources for travelers, such as Tule Tank and Buckhorn Tank, are documented alongside mining evidence at the Venegas Prospects. This map provides a rare look at how the Cabeza Prieta Mountains cross-cut contemporary political and military jurisdictions.
