What is the name of the massive saltwater lake in Utah, USA?

The massive saltwater lake in Utah, USA, is the Great Salt Lake.

The Great Salt Lake is an endorheic lake, meaning it has no river outlet. Water arrives mainly through the Bear, Weber, and Jordan rivers, while evaporation leaves minerals behind. That process makes the lake hypersaline, with salt concentrations that can exceed those of seawater. Its dense water also makes floating unusually easy.

The lake is a remnant of prehistoric Lake Bonneville, which once covered much of western Utah and parts of neighboring states during the Ice Age. When Lake Bonneville shrank, it left behind several smaller lakes, including the Great Salt Lake. Its surface area changes dramatically with rainfall, drought, and upstream water use.

A common mix-up is confusing it with Utah Lake, which is freshwater, or with the Great Salt Lake Desert, a separate dry basin nearby. The lake also supports enormous populations of brine shrimp and migratory birds, making it ecologically important despite its extreme salinity.
