Castle Dome Plain defines the broad, arid expanse of this southwestern Arizona landscape, situated within the transition between several townships including t5s r19w and t6s r18w. The terrain is characterized by intricate drainage patterns and subtle elevation shifts, most notably marked by a Natural Arch in the northeastern section of the quadrangle. This 2014 survey by the U.S. Geological Survey provides a precise topographic look at the land's natural geometry, illustrating the dry washes and alluvial fans that cross the plains. While the map is sparse in terms of modern infrastructure, it preserves the exact location of geological curiosities and official boundary divisions in Yuma County.
