2011 Map of Vopoki Ridge SE

About this map

The Yuma Desert dominates this 2011 survey, revealing an arid landscape defined by expansive drainage patterns along the Arizona-Sonora border. This specific quadrangle covers a section of the Lower Colorado River Valley, where the desert floor is marked by a complex network of dry washes and alluvial fans that move sediment toward the southwest. Unlike more settled regions, the map highlights the stark environmental character of the borderlands, showing a vast, open terrain where natural hydrology remains the primary feature. The absence of built infrastructure within this portion of the Yuma Desert underscores the region's historical role as a challenging corridor for travel and a strictly preserved desert environment.
