2019 Map of Wallace Draw

About this map

The Middle Concho River flows across the southern portion of this landscape in Irion County, where the terrain is defined by a series of deep drainage patterns. Prominent features such as Wallace Draw and Big Hollow Draw cut through the high ground, illustrating the hydrological network that moves water toward the river during infrequent West Texas rains. The area is marked by a network of ranch and county roads, including the uniquely named Hell Hole and its associated Hell Hole Rd. These roads, along with others like Andy Suggs Rd and Cattle Guard 8 Rd, provide access through a landscape largely shaped by intermittent watercourses like Dry Cr. This modern survey by the U.S. Geological Survey offers a clear view of the rural infrastructure and natural topographic depressions that characterize this part of the Edwards Plateau region.
