2019 Map of Cap Rock Butte

About this map

Cap Rock Butte rises above the transition between the Edwards Plateau and the Trans-Pecos, marking a significant elevation point in this arid West Texas landscape. The 2019 survey documents a region defined by complex drainage systems and wide high-elevation basins, most notably the W B Flats in the northwest. Water movement across this terrain is primarily captured by ephemeral watercourses such as Red Mill Draw and Downie Draw, which snake through the limestone topography. This specific area spans the boundary of Pecos County and Brewster County, where human infrastructure is largely limited to the winding path of Longfellow Rd. The map illustrates the stark geography of Big Canyon and surrounding ridges, providing a clear record of the ranching and transit corridors used in modern-day Pecos County.
