2019 Map of Sheffield NW

About this map

Sheffield Draw and Lower Fourmile Draw define the drainage patterns of this corner of West Texas, where the high desert plateau begins to break into steep relief. The landscape is characterized by deep erosional features like Bearfoot Canyon and Surveyor Canyon, which illustrate the arid environment's topography. Human activity is sparse, centered primarily on transportation and ranching infrastructure such as the Canon Ranch Airport in the northern reach and the Seventeen Ranch Rd further south. This 2019 survey captures the area along the Pecos and Terrell county line, revealing a network of remote access routes including Ranch Rd 1217 that service this isolated region of the Trans-Pecos.
