1996 Map of Mount Ajo

About this map

Mount Ajo towers over this section of the Sonoran Desert, where the rugged peaks of the Ajo Range separate the Organ Pipe Cactus National Monument from the Tohono O'odham Indian Reservation to the east. The topography is defined by a series of dramatic drainages including Arch Canyon, Estes Canyon, and the three forks of Alamo Canyon, which descend toward the Alamo Road. Traces of human activity are centered around vital water sources such as Bull Pasture Spring and Barajita Well, reflecting the historical importance of these spots in an arid landscape. To the north, the distinctive landmark of Montezumas Head (I'itoi Mo'o) stands near Pitahaya Canyon, while the southern reaches feature the Diablo Mountains and the loop of Ajo Mountain Drive, providing a detailed look at the intersection of protected wilderness and indigenous lands during the late 1990s.
