Mohave Peak stands as the primary landmark in this arid section of La Paz County, where the desert landscape is defined by an intricate network of drainage channels. The area is heavily marked by the presence of the Yuma Proving Ground, indicating the military significance of this terrain for testing and training operations in the early 21st century. Natural drainage follows the contours of the land through several major systems, including Mohave Wash, Gould Wash, McAllister Wash, and Yuma Wash. These ephemeral watercourses illustrate the hydrologic patterns of the region, showing how water moves from the higher elevations near the peak across the broad desert floor. The map provides a clear record of the boundary and restricted access nature of the proving grounds during this period.
