Tat Momoli Valley defines the western portion of this arid landscape, where the ephemeral Tat Momoli Wash carves its way through the basin floor. The terrain is characterized by broad alluvial valleys framed by sudden elevations, most notably the Sawtooth Mountains in the northeast and the Slate Mountains to the southwest. This 2011 survey captures the natural drainage patterns of the Sonoran desert, showing how runoff from heights like Wildcat Peak feeds into the Aguirre Valley. The lack of man-made structures on the sheet highlights the remote, preserved state of the district, making it an essential reference for understanding the physical geography and natural landmarks such as Silver Reef Wash before any future regional development.
