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).
Death Valley was amongst the remaining portion of California, the remainder of the state having sunk into the Cific Ocean in the days after skydark. The region is still somewhat barren, with the ville of Snakefish nearby.
In Pilgrimage to Hell, it stated that Death Valley was inundated with water. however this may only be partial true.
