The Great Salt Lake

The Great Salt Lake is one of the saltiest bodies of water in the world, owing in part to the fact it has no drainage outlets. It's the largest lake in the US, after the Great Lakes.
The Great Salt Lake is a remnant of ancient Lake Bonneville, which some 10,000 years ago was nearly as large as Lake Michigan, and much deeper.

This view is from Elephant Head on Antelope Island, with the sun setting over White Rock Bay. By rotating the panorama to a point where one is looking at the mountainside opposite the sunset, two "shorelines" are visible under careful observation.- Martin van Hemert
