Great Salt Lake

Great Salt Lake

geographical name

Lake, northern Utah, U.S. It is the largest inland body of salt water in the Western Hemisphere and one of the most saline in the world. It fluctuates greatly in size, depending on rates of evaporation and the flow of the rivers into it. Its surface area has varied from about 2,400 sq mi (6,200 sq km) at its highest levels in 1873 and the mid 1980s to about 950 sq mi (2,460 sq km) at its low level in 1963. At times of median water level, it is generally less than 15 ft (4.5 m) deep. Surrounded by stretches of sand, salt land, and marsh, the lake remains isolated, though in recent years it has become important as a source of minerals, as a beach and water-sports attraction, and as a wildlife preserve.
