Death Valley is a desert valley located in Eastern California. It is the lowest, driest, and hottest area in North America. Death Valley's Badwater Basin is the point of the lowest elevation in North America, at 279 feet (85 m) below sea level. This point is 84.6 miles (136.2 km) east-southeast of Mount Whitney, the highest point in the contiguous United States with an elevation of 14,505 feet (4,421 m). Located near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve. It is located mostly in Inyo County, California. It runs from north to south between the Amargosa Range on the east and the Panamint Range on the west; the Sylvania Mountains and the Owlshead Mountains form its northern and southern boundaries, respectively. It has an area of about 3,000 sq mi (7,800 km2). The highest point in Death Valley itself is Telescope Peak in the Panamint Range, which has an elevation of 11,043 feet (3,366 m).
The Amargosa Range is a mountain range in Inyo County, California and Nye County, Nevada. The 110-mile (180 km) range runs along most of the eastern side of California's Death Valley, separating it from Nevada's Amargosa Desert. The mountain range is named after the Amargosa River, so-named for the Spanish word for bitter because of the bitter taste of the water. In order from north to south, the Grapevine Mountains (including the range's highest point, 8,738 feet (2,663 m) Grapevine Peak), the Funeral Mountains, and the Black Mountains form distinct sections. Many of Death Valley National Park's most well-known features, such as Zabriskie Point and Artists Drive are located in or are part of the Amargosa Range.
The Panamint Range is a short rugged fault-block mountain range on the northern edge of the Mojave Desert, in Death Valley National Park. The range runs north-south for approximately 100 miles (160 km) through Inyo County, forming the western wall of Death Valley and separating it from the Panamint Valley to the west. The range is part of the Basin and Range Province, at the western end of the Great Basin. The highest peak in the range is Telescope Peak with an elevation of 11,049 feet (3,368 m).
