Oak Hills dominate the southern portion of this Presidio County landscape, where elevation contours reveal a series of ridges and valleys typical of the Trans-Pecos region. In the northern reaches, the terrain levels out into a wide basin drained by Ryan Draw, a significant watercourse that carves its way through the highland flats. This modern survey illustrates a remote ranching environment defined by limited infrastructure, where access is provided primarily by Richards Gate Rd and Richard Gates Rd. The sparse placement of these routes suggests a landscape of large-scale landholdings and open range. As part of a series produced by the U.S. Geological Survey, this sheet provides a clear spatial perspective of the natural drainage patterns and topographical transitions that characterize the high desert south of the Ryan siding area.
