1996 Map of West of Pisinimo

USGS Topo · Published 2001

About this map

The Quijotoa Valley dominates this landscape within the Tohono O'odham Indian Reservation, showing a vast system of desert drainages. Topography compiled in the 1960s was updated with 1990s planimetry to illustrate the subtle shifts in the arid terrain before the turn of the millennium. The seasonal hydrology of the region is defined by the San Simon Wash and the Gu Vo Wash, which channel water through the alluvial fans of the valley floor. These washes represent critical landmarks in a region where water flow dictates both the natural environment and historical land use patterns. The map provides a clear look at the township and range lines, including the boundary between T 15 S and T 16 S, which helps orient researchers to the specific surveyed sections of this part of Pima County.
