2019 Map of Sonora NW

About this map

Dry Devils River defines the drainage patterns of this high plains landscape, cutting through the Edwards Plateau where Schleicher and Sutton counties meet. The arid environment is characterized by ephemeral water systems like Meckel Draw and engineered water management, notably the Soil Conservation Service Site 4 Reservoir and Soil Conservation Service Site 7 Reservoir. This map documents a modern network of private and county roads, including Co RD 113 and PVT RD 1158, which provide access across the vast ranchlands. The topography is defined by intricate contouring that illustrates the many small draws and ridges typical of the West Texas Divide region, showing how human infrastructure adapts to the natural desert-scrub geography.
