2018 Map of West of Pisinimo

About this map

Quijotoa Valley dominates this arid landscape in the Pisinemo District of Pima County, where the desert floor is defined by a sparse network of ephemeral drainages and a single primary transit route. The northern reaches of the map show the broad expanse of the valley, while the eastern edge is marked by the course of San Simon Wash. Running east-to-west through the center of the sheet, Indian Rte 28 provides the only significant modern infrastructure across the terrain. Hydrological patterns are further illustrated by the Gu Vo Wash, which meanders through the southern sections. This 2018 survey captures the region's topographical character through clear contouring, documenting the fundamental water courses and township boundaries like t15s r2w that organize this remote desert geography.
