Big Valley dominates the central landscape of this late-1970s survey, where the border between Utah and Arizona meets the boundary of Washington and Mohave counties. The terrain is defined by a network of drainage systems including Lizard Wash, Mokaac Wash, and Atkinville Wash, which converge as they move through the valley floor. Water management is a primary feature of this arid environment, evidenced by several strategically placed improvements such as the State Line Reservoir, Mokaac Reservoir, and the North Tank.
