About this map

The Barajita Valley and La Quituni Valley dominate this Pima County landscape, where desert washes define the movement of water and travel. Small settlements like Pia Oik, Siovi Shuatak, and Sweetwater are connected by Indian Rte 1 and Rte 1 BIA, reflecting the enduring human presence in this arid basin. The southwestern portion of the map includes a section of the Organ Pipe Cactus National Monument, where the terrain rises sharply into the Ajo Range.

Notable mountain passes such as Siovi Shuatak Pass, Pia Oik Pass, and Ali Wua Pass serve as critical geographic transitions between the valleys and the surrounding peaks, including the Mesquite Mountains and Sierra de Santa Rosa. These features, alongside drainage networks like Pia Oik Wash, provide a detailed look at the hydrology and topography that dictate the ranching and tribal settlement patterns of the region.
