The Dead Sea, "Sea of Salt", , Yām HaMā́weṯ, "The Sea of Death, also called the Salt Sea, is a salt lake bordering Jordan to the east, and Israel to the west. Its surface and shores are 429 metres (1,407 ft) below sea level, Earth's lowest elevation on land. The Dead Sea is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With 34.2% salinity (in 2011), it is also one of the world's saltiest bodies of water, though Lake Vanda in Antarctica (35%), Lake Assal (Djibouti) (34.8%), Lagoon Garabogazköl in the Caspian Sea (up to 35%) and some hypersaline ponds and lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond (44%)) have reported higher salinities. It is 9.6 times as salty as the ocean. This salinity makes for a harsh environment in which animals cannot flourish, hence its name. The Dead Sea is 50 kilometres (31 mi) long and 15 kilometres (9 mi) wide at its widest point It lies in the Jordan Rift Valley and its main tributary is the Jordan River.
