2011 Map of West of Ventana

About this map

San Simon Wash and its complex network of seasonal tributaries define the landscape of this Pima County desert region. This 2011 survey illustrates a sparse infrastructure where the natural drainage patterns of the Sonoran desert dictate the few routes that cross the terrain. Human activity is represented primarily by designated tribal road systems, including Indian Rte 23 and Indian Rte 34, which provide the only reliable transit through this arid territory. The topographic detail focuses on the subtle elevation changes of the desert floor and the drainage basins that feed into Kaka Wash, highlighting the importance of water management and natural geography in a region where surface water is transitory and significant.
