2011 Map of North of Isla Pinta

About this map

The dry washes and desert expanses of Yuma County are documented in this 2011 survey, showing the vast alluvial fans that spread across the landscape. The northern reaches of the Sierra Pinta anchor the southwest corner, while the Mohawk Mountains rise in the northeast, framing a broad valley defined by intricate drainage patterns. This map illustrates the stark geography of the Sonoran Desert, where ephemeral watercourses create a dense network of braided channels across the valley floor. Aside from a few light-duty and unimproved roads that cut straight paths through the terrain, the area remains largely undisturbed by modern development, preserving the natural drainage morphology of this arid environment.
