The Cabeza Prieta National Wildlife Refuge and Organ Pipe Cactus National Monument converge in this arid corner of Pima County, reflecting a landscape defined by conservation and remote water sources. The drainages of San Cristobal Wash course through the terrain, connecting isolated landmarks like Jose Juan Tank and the eponymous Pozo Nuevo Well. These water points were historically critical for movement through the Sonoran Desert. The map is anchored by the desert peaks of the Agua Dulce Mountains, Quitobaquito Hills, Cipriano Hills, and Bates Mountains, which create a complex system of ridges and basins that have long shaped travel and land use along this international border region.
