About this map

Siovi Shuatak and the settlement of Pia Oik anchor this high-desert landscape in the Tohono O'odham Nation during the early 21st century. The map reveals a complex system of drainage basins where the Siovi Shuatak Wash and Pia Oik Wash navigate between several prominent landforms, including the Gu Vo Hills and the northern reaches of the Ajo Range. Transport in this arid region is defined by Route 1 Bia and Indian Rte-1, which provide the primary connectivity through the wide corridors of the Barajita Valley and Pia Oik Valley.

Beyond the sparse settlements, the map details the transition between various geological features, from the Sierra de Santa Rosa in the southwest to the Mesquite Mountains on the eastern edge. This survey documents the modern infrastructure and traditional place names of the area, providing a clear record of the relationship between seasonal watercourses and the established communities at Sweetwater and Pia Oik Pass.
