What is the saltiest body of water on the planet?
Hidden away in a dry Antarctic valley, Don Juan Pond is known as the saltiest body of water on planet Earth. It is a small and very shallow hyper-saline lake in the west end of Wright Valley, Victoria Land, Antarctica. It is wedged between the Asgard Range to the south and the Dais Range to the north. With a salinity level of over 40%, Don Juan Pond is the saltiest known body of water on Earth.
It is claimed that Don Juan Pond has over 18 times the ocean's salinity and 1.3 times that of the Dead Sea. The fact that it is the only Antarctic hype-saline lake of several that almost never freezes, is an indication of its top rank in salinity among the world's lakes.
