2021 Map of Santa Rosa Mountains SE

About this map

Santa Rosa Mountains and their southeastern foothills define the landscape of this Pima County desert region. The terrain is characterized by broad alluvial valleys and intermittent drainage channels such as Sil-Nakya Wash, which carries seasonal runoff through the arid basins. Settlement is sparse, represented by small communities like Hoi Oidak and Pipyak, which are situated along the lower elevations where the terrain transitions from the rocky slopes of the Sil Nakya Hills to the floor of Pipyak Valley. The map illustrates a traditional desert geography where human habitation is concentrated near the base of prominent ranges. High points like the Vaca Hills stand as distinct landmarks above the desert floor, while the layout of township and range boundaries across the landscape highlights the formal land management of the Tohono O'odham Nation territory.
