The Great Salt Lake is the largest saltwater lake in the United States.

Located in the northern part of Utah, the Great Salt Lake is a remnant of the ancient Lake Bonneville. It is the largest saltwater lake in the U.S. by surface area, covering about 1,700 square miles at its full size. The lake's salinity varies, but it is much saltier than seawater, which gives it its distinctive name. The Great Salt Lake is an important ecological site, providing habitat for migratory birds and supporting a variety of recreational activities.
