Big Bend National Park

From the U.S. Department of the Interior:

This magical place is Big Bend National Park in Far West Texas. With an elevation ranging from less than 1,800 feet along the Rio Grande to nearly 8,000 feet in the Chisos Mountains, Big Bend includes massive canyons, vast desert expanses, forested mountains and an ever-changing river. Here you can explore one of the last remaining wild corners of the United States. Photo by Erik A. Walker. — at Big Bend National Park.
