South Mustang Draw and a complex network of ephemeral watercourses define this West Texas landscape along the high divide between the Concho and Colorado River watersheds. The terrain is marked by deep erosional features like Big Jim Draw and Isaac Draw, which reveal the underlying drainage patterns of Irion and Reagan counties. The jurisdictional boundary between Reagan and Irion counties runs north-to-south through the eastern portion of the sheet, cutting across the upper reaches of West Hollow. Transportation in this ranching country is dictated by the rugged topography, with local routes such as Rocker B Ln and Rocky Rd providing access to the remote uplands and draws. This modern survey illustrates the persistent importance of natural drainage features in an arid environment, where names like Antelope Draw and Lewis Draw serve as primary geographic markers.
