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
Nevada State Route 373 Valley come into view. The route continues north from here to its terminus at US 95, near the former site of Lathrop Wells. An unimproved road through Amargosa Valley, connecting Nevada to Death Valley Junction, appears on state maps as early as 1927. This route crossed the state line roughly where the current highway crosses now, but instead veered northwest to State Route 5 (now US 95) southwest of Beatty near the now defunct town of Caracca. The road, which paralleled the tracks of the Tonopah and Tidewater Railroad to the west, was recognized as State Route 29 by 1932.
