Mohawk Mountains rise sharply along the western edge of this arid landscape, defining the rugged topography of the Sonoran Desert in Yuma County. These peaks contrast with the broad drainage of the San Cristobal Valley to the east, where the ephemeral San Cristobal Wash meanders northward. This 2018 survey provides a clear view of the sparse water resources and terrain that shaped travel and habitation in this corner of Arizona, centered on the remote Monreal Well. The map serves as a detailed record of the township and range system, documenting the precise boundaries of t11s r12w, t11s r11w, t12s r12w, and t12s r11w across an environment defined by extreme relief and desert hydrology.
