The boundary between Val Verde and Edwards Counties bisects this high-elevation landscape, where the seasonal drainage network of the Dry Devils River watershed dominates the topography. This 2019 survey captures the vast, arid terrain of the Edwards Plateau, characterized by a complex system of draws that channel rare rainfall into the river basin. The most prominent feature is the winding course of the Dry Devils River, which is fed by significant tributaries like County Line Draw and South Buckley Draw. Transport through this cattle-ranching country is anchored by Highway 277, which cuts a nearly straight line north-south across the high ground between the river and Dolan Creek. The map provides a clear record of these intermittent watercourses, including Turney Draw and Big Turney Draw, which define the eastern reaches of the quadrangle.
