Located near the Dallol crater in Ethiopia’s Danakil Depression is Gaet’ale Pond, a small pool of water with a salinity of 43%, making it by far the saltiest body of water on Earth.
To put into perspective just how salty Gaet’ale actually is, you should know that the Dead Sea, the world’s most famous hypersaline body of water, has a salinity of 33.7%, while the world’s oceans have an average salinity of 3.5%. The water in this small pond is so overly saturated with iron salts that it feels greasy on the hand, as if it were oil. The locals in this part of Ethiopia sometimes call it “oily lake”, because of how oily the water feels. But some call it “killer lake”, because of the toxic gases emitted through the surface of the water, and the perfectly preserved carcasses of birds and insects on its shores are warning of the danger of getting too close to the water.
