BAYLOR MOUNTAINS. The Baylor Mountains begin two miles north of Van Horn and stretch nine miles to the north, terminating south of Salt Lake in western Culberson County (with their center at 31°15' N, 104°46' W). The highest elevation in the mountains is 5,564 feet above sea level. The Baylors are part of an uplifted fault block that includes the Sierra Diablo and Beach Mountains and forms the steep west flank of the salt flats. The Baylors are capped by Permian Hueco limestone, some 250 million years old. Ordovician and Silurian rocks, from 400 to 500 million years old, are exposed on their eastern flank; exposed Silurian rocks are relatively rare in the western United States, so the Baylors are of some interest to geologists studying that period. The Baylors are steep and rocky, with local deep and dense dissection. On them a surface of shallow, stony soil supports oaks, live oaks, piñons, mesquites, junipers, and grasses. The mountains are named for Col. George W. Baylor, who led the Texas Rangersqv against the Mescalero Apaches in this region in the late nineteenth century.
