The settlement of Chispa anchors this high-desert landscape in Jeff Davis County, where the sprawling Lobo Valley meets the rising slopes of the Sierra Vieja mountains. This map documents a sparsely populated ranching territory defined by seasonal watercourses like Wild Horse Cr, Wild Horse Draw, and Tally Slough. The topographic detail reveals a complex network of canyons and passes, most notably Ninetysix Canyon and Ninetysix Gap, which provide natural corridors through the terrain. Human presence is largely defined by extensive ranching infrastructure, as seen in the routes of Means Ranch Rd and White Ranch Rd. The isolated peak of Little Flattop stands as a distinct landmark against the broad valley floor, illustrating the stark elevation changes that characterize this portion of the Trans-Pecos region.
