2011 Map of Aguila Mountains SW

About this map

San Cristobal Wash dominates the arid landscape of this Yuma County quadrangle, carving a wide braided path from the northwest toward the southeast. The terrain is defined by these seasonal drainage patterns, where water moves across the desert floor only during significant rain events. In the eastern portion of the map, the Growler Valley opens up, drained by the tributary Growler Wash. This 2011 survey by the U.S. Geological Survey illustrates the stark geomorphology of the region, where the alluvial fans and dry washes provide the only navigable features across the open desert floor. The lack of permanent structures or roads emphasizes the isolation of this corner of Arizona, preserved here in a detailed topographic record of its natural hydrology.
