There's a lake in the Rift Valley so hot and acidic only bacteria can survive in it, according to NBC News. More curiously, the lake's outer edges perfectly preserve any animal unfortunate enough to fall into its waters.
Lake Natron, located in Tanzania, builds it deadly waters with run off from the million-year-old volcano, Ol Doinyo Lengai, stands on the lake's southern edge, NBC News reported. Because it spews a unique kind of "cool, runny, dark" lava known as natrocarbonatites, the volcano is the only of its kind. Thus, Lake Natron is one of a kind as well.
