About this map

The Great Colorado Valley defines the central topography of this desert landscape, framed by the jagged silhouettes of the Trigo Mountains and the Dome Rock Mountains to the north. This modern survey illustrates the complex drainage network characteristic of the Arizona desert, where numerous ephemeral watercourses like Trigo Wash, Weaver Wash, and Mohave Wash carve deep into the basin floor. These washes serve as the primary geological features connecting the higher elevations of the North Trigo Peaks and South Trigo Peaks to the valley below.

Transportation through this arid reach is limited to rugged corridors such as the Ehrenberg-Cibola Rd and Cibola Rd, which navigate the terrain between the mountain ranges. The map provides a clear look at the public land survey system divisions, including T1N R21W and T2N R22W, which are essential for property and boundary research in this part of La Paz County. The lack of permanent settlements highlights the remote and preserved nature of the wilderness surrounding Peters Wash and Mule Wash.
