Frio River drainage patterns define this South Texas landscape in Frio County, characterized by a complex network of seasonal creeks and livestock tanks. Prominent elevation markers include the English Hills in the southwest and Pilot Knob to the east, which overlook a terrain shaped by the ranching economy. The distribution of numerous water catchments, such as Willow Tank, Tutiga Tank, and Llave Tank, illustrates the essential infrastructure required for land management in this arid region.
