Death Valley National Park Death Valley National Park Death Valley National Park is an American national park that straddles the California—Nevada border, east of the Sierra Nevada. The park occupies an interface zone between the arid Great Basin and Mojave deserts, protecting the northwest corner of the Mojave Desert and its diverse environment of salt-flats, sand dunes, badlands, valleys, canyons, and mountains. Death Valley is the largest national park in the lower 48 states, and the hottest, driest and lowest of all the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is below sea
Death Valley then radiated upward, but the dense below-sea-level air absorbs some of this radiation and radiates some of it back towards the ground. In addition, the high valley walls trap rising hot air and recycle it back down to the valley floor, where it is heated by compression. This process is especially important in Death Valley, as it provides its specific climate and geography. The valley is surrounded by mountains, while its surface is mostly flat and devoid of plants, so much of the sun's heat can reach the ground, absorbed by soil and rock. When air at ground level is
