2021 Map of West of Pisinimo

About this map

Quijotoa Valley dominates this arid landscape within Pima County, where the desert floor is defined by a series of significant drainage systems. The northern reaches are marked by the branching network of San Simon Wash, while Gu Vo Wash cuts across the southern half of the quadrangle. Transport through this remote section of the Sonoran Desert is limited primarily to Indian Rte 28, which follows the natural contours of the valley floor. The map documents the vast, open character of the region, emphasizing the importance of these seasonal watercourses in shaping the local topography and historical access routes through the Arizona desert.
