Big Bend National Park
Big Bend National Park, located along the U.S.-Mexico border in Texas, is the largest protected area of Chihuahuan Desert in the United States, covering 1,253 square miles. The park ranges in elevation from 1,800 feet along the Rio Grande to 7,800 feet in the Chisos Mountains. This range in elevation contributes to variations in moisture and temperature, which contributes to a high level of diversity in the park’s plant and animal communities. Big Bend is also at the edge of many plant and animal ranges. Latin American species, many from the tropics, range this far north, while northern-nesting species often travel here in winter. The park is well known for its geology and more types of birds, bats, and cacti have been documented here than any other national park in the United States.
