2011 Map of Santa Rosa Mountains SE

About this map

The Santa Rosa Mountains dominate the western portion of this Pima County landscape, giving way to the expansive desert drainage systems of the Sif Oidak District. Small, localized settlements such as Hoi Oidak and Pipyak are positioned along the fringes of the highlands, where the topography transitions into the Pipyak Valley. This 2011 survey documents a complex network of seasonal watercourses, most notably the Sil Nakya Wash, which snakes through the terrain toward the Sil Nakya Hills. The map illustrates the geographical relationship between these mountain ranges and the adjacent Aguirre Valley to the east, anchored by landmarks like Gu Achi Peak. For those studying the tribal lands of southern Arizona, the document provides a clear view of the natural landmarks and scattered habitations that define the modern land-use patterns of the Tohono O'odham Nation.
