2014 Map of West of Pisinimo

About this map

The Quijotoa Valley dominates the northern reaches of this Pima County landscape, where the ephemeral drainage patterns of the Sonoran Desert are clearly delineated. Flowing across the arid terrain, the San Simon Wash and the extensive network of the Gu Vo Wash define the local hydrology, providing critical points of reference in a region characterized by broad alluvial plains and isolated desert peaks. This 2014 survey captures the area within the Pisinemo District, highlighting the intersection of Bureau of Indian Affairs routes like BIA-28 with the natural geography. The map illustrates how these desert washes serve as the primary topographical features, tracing the seasonal movement of water through the valley floor and across the township boundaries of T15S and T16S.
