PUNTA DE LA SIERRA. The Punta de la Sierra (centered at 29°06' N, 103°19' W), also known as the Picachos or the Pinnacle Mountains, is five miles northeast of the Johnson Ranch in Big Bend National Park in southern Brewster County. At an elevation of 4,885 feet above sea level, this southern escarpment of the Chisos Mountains rises some 2,830 feet above Reed Camp on the Rio Grande, three miles south. Shallow stony soils in the area support live oak, piñon pine, juniper, and grasses.
