2022 Map of Sanderson SE

About this map

Sanderson Canyon and Seminole Canyon dominate this high-relief terrain in Terrell County, illustrating the intricate drainage patterns of the Trans-Pecos region. The landscape is defined by deep incisions through limestone plateaus, most notably along Sanderson Cr. Unlike more developed areas, the human footprint here is limited to a sparse network of ranch and access roads such as Bone Water Rd and Carruthers Rd, which follow the contours of the high ground between the canyons. The mapping of Isinglass Canyon in the southwest corner highlights the convergence of these dry wash systems. This 2022 data reflects the modern conservation and land management of this arid environment, where water flow is intermittent but has shaped every visible ridge and draw.
