Sierra Blanca

Sierra Blanca is a prominent volcanic mountain in far West Texas that rises abruptly from the Chihuahuan Desert near the town of Sierra Blanca. At 6,892 feet, it is the highest point in its range and one of Texas's most topographically prominent peaks, standing out as a major landmark along Interstate 10. Formed when late Oligocene rhyolite intruded into older Cretaceous limestone, shale, and sandstone, it dominates an arid landscape where limited runoff eventually reaches the Rio Grande. Its Spanish name, meaning White Mountain, likely dates to the era of Francisco Vázquez de Coronado, and the nearby town later took its name from the mountain.
