1990 Map of Isla Pinta

About this map

The Sierra Pinta range dominates this landscape, carving a sharp spine between the Mohawk Valley to the northeast and the Tule Desert to the southwest. This territory is strictly managed, falling within the Barry M Goldwater Air Force Range and the Cabeza Prieta Wilderness and National Wildlife Refuge. The map provides a detailed look at the arid hydrology of the region, featuring crucial desert water catchments like Heart Tank and Eagle Tank. Navigational markers through the high ground include Sunday Pass, while the eastern slopes are dissected by numerous drainage systems such as Hummingbird Canyon, Chia Canyon, and Eagle Canyon. The presence of large restricted zones underscores the area's dual role as a sensitive ecological sanctuary and a strategic military training ground during the late twentieth century.
