McPherson Wash drains the arid expanse of Yuma County in this 2011 topographic survey. The landscape is defined by its scarce water sources, which were historically vital for transit and survival in this corner of Arizona. Vital catchments and improvements like Little White Tanks and Figueroa Tank dot the drainage basins. The eponymous Kofa Deep Well sits in the northeast, marking a specific point of groundwater access amidst the desert terrain. Primary access through this region is provided by the unpaved corridor of King Rd, which traverses the landscape from northwest to southeast, cutting across the natural flow of the washes.
