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.
1 The maximum air temperature for that day was 128Â°F. 2  Average rainfall at Death Valley is less than 2 inches per year. 3  In some years, it's even less. 4  That's because storms moving inland from ocean lose water when they pass over mountains-and there are four major mountain ranges between Death Valley and the Pacific.
