2011 Map of Pinta Playa

About this map

Sierra Pinta defines the character of this desert landscape in Yuma County, appearing as a series of complex ephemeral drainage patterns carved into the arid terrain. The 2011 survey focuses on the stark topography of the Lower Colorado River Valley region, dominated by the dry lake bed of Pinta Playa in the southwest corner. The map illustrates a network of desert washes that converge and diverge across the basin, highlighting the natural hydrological flow of the area. This edition records the area as it existed in the early twenty-first century, showing a region largely defined by its natural features rather than human development or infrastructure.
