There's a lake that's actually a giant sinkhole - Apparently.
Lake Natron, located in Tanzania, is a saltwater lake that's actually a giant sinkhole, formed by the collapse of a volcanic caldera. The lake's waters are so caustic that they can preserve dead animals, turning them into eerie, calcified statues. The lake's surface is also a breeding ground for millions of red algae, which gives the water a distinctive red color. Despite its surreal appearance, Lake Natron is a real geological wonder, and its unique properties have made it a popular destination for scientists and photographers.
