9 . The Dead Sea might be the most famous saline body in the world, but it’s by no means the only one. Here, we uncover some other salt lakes around the world.

Dead Sea

The most famous of the lot, the Dead Sea—also known as the Salt Sea—is a natural place to start. It’s technically not a sea at all, but a land salt lake. Its waters are mainly drawn from the Jordan River, and the high salinity (盐度) means no life can survive here, so don’t expect any colorful fish. However, much amusement results from the sea’s buoyancy (浮力): Bring some reading material to the waters and lie back—nature will do the rest.

Lake Assal

Surrounded by black volcano rocks, Lake Assal takes the title of being the lowest point in Africa. Vast salt fields mark its edges; the lake has long been at the centre of the area’s salt trade, on which the region’s African locals still rely. Though the area might not be suitable to live in, the waters are rich in minerals and related to health benefits.

Great Salt Lake

The biggest salt lake in the western hemisphere, and the one that gave Salt Lake City its name, the Great Salt Lake finds its home in northern Utah. What makes the lake well-known is not only the lake’s blue and green waters and white-sand beaches, but also Great Salt Lake State Park and Antelope Island State Park, both offering super hiking and biking trails, and great long views.

Don Juan Pond

Don Juan Pond might not win any prizes for its beauty—at four inches deep, it’s little more than a pond, but it is worth visiting. Its salinity content of almost 40 percent   makes it   one   of   the   saltiest   bodies   of   water   on   Earth, meaning it doesn’t freeze even when Antarctic temperatures drop to -50℃. And with suggestions that water in a similar form could exist on Mars, there’s more than one reason for scientists to study this fascinating dry, cold environment.
