King Valley dominates the southwestern portion of this 2011 survey, illustrating a wide drainage system within the arid landscape of Yuma County. The terrain is defined by the prominent Neversweat Ridge which rises toward the center of the sheet, while the northern boundary is marked by the rugged reaches of the Tank Mountains. This topographic study by the U.S. Geological Survey captures the intricate network of desert washes and seasonal watercourses that shape the valley floor, alongside a sparse collection of secondary roads and 4WD tracks. These paths provide the primary access through the desert, connecting the elevations of the ridge to the surrounding lowlands in an area characterized by its minimal human development and striking geological relief.
