CHISOS MOUNTAINS

Chihuahuan Desert and the Chisos Mountains in the background, Big Bend National Park, Texas southernmost segment of the Rocky Mountains, covering 40 square miles (104 square km) along the Rio Grande in southwestern Texas, U.S. They form the state's third highest mountain group, culminating at Emory Peak (7,777 feet ). The mountains are within Big Bend National Park, and tourists are attracted by their self-guiding trails, unique geologic formations, and spectacular scenery. Chisos has been interpreted as an Indian word for "ghost," or "spirit," or as having come from the Castilian hechizos ("enchantment").
