Visitors come to Death Valley to experience the stark and lonely vastness of the valley; the panorama of rugged canyons and mountains; the pleasures of the dry, moderate winter climate; the challenge of the hot, arid summer; the relief of the cooler mountains; and the reminders of frontier and Native American ways of life. Yet Death Valley National Park's greatest value is as an outdoor natural history museum.

It contains fine examples of most of the earth's geological eras and the forces that expose them. Plant and animal species, some of which occur nowhere else in the world, have adapted to the harsh desert environment here in remarkable ways. Extremes of climate and geography make it the ultimate showcase of American deserts.

Death Valley National Park includes all of Death Valley, a 156-mile-long north/south-trending trough that formed between two major block-faulted mountain ranges: the Amargosa Range on the east and the Panamint Range on the west. Telescope Peak, the highest peak in the Park and in the Panamint Mountains, rises 11,049 feet above sea level and lies only 15 miles from the lowest point in the United States in the Badwater Basin salt pan, 282 feet below sea level. The California Desert Protection Act added most of the Saline, Eureka, northern Panamint, and Greenwater valleys to the Park.
