The Galiuro Mountains dominate the eastern landscape of this quadrangle, falling away into a series of deep drainage networks and canyons. This arid region at the junction of Graham, Pinal, and Pima counties is defined by its water management and erosion patterns, featuring the San Pedro River in the southwest corner and the expansive Coronado National Forest to the northeast. Traces of human activity are centered around seasonal water sources and livestock infrastructure, such as YLE Tank and the named settlement at Charlie Dike.
