2019 Map of Sanderson SE

About this map

Sanderson Canyon and Seminole Canyon dominate this high-desert reach of Terrell County, where deep drainage networks carve through the limestone plateau. The landscape is defined by its seasonal watercourses, notably Sanderson Cr, which snakes through the primary canyon floor. A sparse network of ranch roads provides the only access to this remote territory, many named for local families and landmarks. Historical land use is suggested by routes such as Bone Water Rd and Gatlin Rd, which navigate the complex topography between the primary canyons and Isinglass Canyon in the southwest corner. The map captures the area in the late 2010s, showing how modern transportation routes like US Route 90 follow the natural contours established by the canyon systems.
