Death Valley National Park is a national park in the U.S. states of California and Nevada located east of the Sierra Nevada in the arid Great Basin of the United States. The park protects the northwest corner of the Mojave Desert and contains a diverse desert environment of salt-flats, sand dunes, badlands, valleys, canyons, and mountains. It is the largest national park in the lower 48 states and has been declared an International Biosphere Reserve. Death Valley National Park is visited annually by more than 825,000 visitors who come to see its diverse geologic features, desert wildlife, historic sites, scenery, and clear night skies.
It is the hottest and driest of the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is 282 feet (86 m) below sea level. The park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, Bighorn Sheep, Coyote, and the Death Valley Pupfish, a survivor of much wetter times. The park covers an area of 5,270 square miles (13,649 km2) of which 5,194 square miles (13,452 km2) is federal land. Approximately 95% of the park is a designated wilderness area, which covers 4,774 square miles (12,360 km2), making it the largest in the contiguous 48 states, and the sixth largest in the United States overall.
