About this map

The W Nueces River carves a winding path through this portion of Edwards County, defining a landscape of deep drainage channels and water catchment points. This modern topographic study reveals a terrain shaped by seasonal hydrology, where numerous named features such as Newberry Draw, Fourmile Draw, and Government Draw converge toward the river valley. The presence of the Wiley Waterhole in the southeastern quadrant serves as a critical geographic marker in this arid region, where water sources often dictated land use and ranching boundaries.

Transportation and infrastructure are represented by the corridor of Ranch Rd 674, which parallels the river, and the isolated Pinon Ranch Airport near the southern edge of the sheet. Other hydrologic features like E Fork Sycamore Cr and Cherry Cr illustrate the complex watershed system that feeds into the larger river network, providing essential data for those studying the environmental history of the Edwards Plateau.
