1965 Map of Isla Pinta

About this map

Mohawk Valley and the Tule Desert dominate this mid-century desert landscape, where the arid environment is defined by expansive washes and jagged mountain ranges. Large portions of the territory are managed as the Luke Air Force Range and the Cabeza Prieta Game Range, highlighting the shift toward federal conservation and military use in the Yuma region. The rugged spine of the Sierra Pinta cuts through the center of the sheet, featuring named crossings such as Bean Pass and Sunday Pass. Traces of human activity are sparse, consisting primarily of isolated water sources like Sahara Tank and Isla Pinta, alongside a few unnamed prospects and a network of jeep trails. To the southwest, the Cabeza Prieta Mts rise from the desert floor, with Christmas Pass providing a named point of transit between the peaks.
