Death Valley, California, is the largest national park in the contiguous United States: 3.4 million acres of desert vastness. At first glance it appears to be a barren wasteland, to be hurried through as quickly as possible, but the alert visitor soon recognizes that there is much here to see and experience.
Death Valley has the hottest summers in the Western Hemisphere, and is the only known place in the United States where nighttime temperatures sometimes remain above 100Â°F. The highest average annual temperature in the world, possibly a world record, is the 94Â°F, at Dalol (or Dallol), Ethiopia.
