Death Valley National Park is an American national park that straddles the California–Nevada border, east of the Sierra Nevada. The park boundaries include Death Valley, the northern section of Panamint Valley, the southern section of Eureka Valley and most of Saline Valley. 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 National Park is the hottest, driest, and lowest of the National Parks. The park offers a unique ecosystem quite unlike what most of us have seen before. Most of the park resides at 282 feet below sea level. Yet the park also has tall, snow-crested peaks. Most of the park is an extremely dry, harsh desertscape, yet the park's many oases offer a peaceful and verdant reprieve from the sun-scorched land.
