　　Death Valley is an arid, depressed, desert region, southeastern California. It was given its name by one of 18 survivors of a party of 30 attempting in 1849 to find a shortcut to the California goldfield. Much of the valley is below sea level, and near Badwater at 86 meters below sea level, is the lowest point in the western hemisphere. Death Valley National Monument (established 1933) has an area of 8368.1 sq km and incorporates the valley and surrounding mountains. The valley is from 6 to 26 km wide and about 255 km long and is almost entirely enclosed by mountain ranges, volcanic in origin, bare and brilliantly colored. The Panamint Range on the west, which rises to a maximum altitude of 3367 m in Telescope Peak, shuts out the moist Pacific winds. On the east are the peaks of the Amargosa Range. The summer temperatures in Death Valley, one of the hottest regions known, exceed 51.7 C in the shade and rarely fall below 21.1 C. The National Weather Service recorded 56.7 C IN 1913, the highest temperature ever recorded in the US. Average rainfall in a normal year is less than 51 mm. Sandstorms and dust whirlwinds of several hours duration are common. Several watercourses enter the valley, among them the Amargosa River from the south and Furnace Creek from the east, but it is only after heavy rains, which are rare, that they contain water. The lowest parts of the valley floor are salt flats, devoid of vegetation; higher portions contain a mixture of sand and salt grains, occasionally forming dunes. The western side of the valley floor is bordered by stunted mesquite, and in a marsh in the northern section a growth of tall, coarse grass is found; the east and west slopes have a sparse vegetation of cacti and desert shrubs and grasses. Animal life is confined to a few species of desert reptiles, such as horned toads and lizards and such mammals are as rabbits, rats, and the desert bighorn sheep. Gold has been found in Death Valley, and silver, copper, and lead have been taken in paying quantities. The famous borax deposits of Death Valley were first mined in the 1880s.
