The Great Salt Lake is located in a closed basin within the state of Utah, in the United States. It is a saline lake that is notable for its high salinity due to the lack of an outlet, which causes minerals to accumulate over time. The lake is a remnant of the ancient Lake Bonneville and is important for local wildlife, especially migratory birds. Its unique ecosystem draws researchers and visitors, but its size and salinity have been affected by water diversion and climate change.
