There's a lake that's a "dead" lake - Apparently.
Lake Vida, a 20-kilometer-long lake in Antarctica, has been sealed off from the outside environment for thousands of years. The lake's water is in contact with the atmosphere only through a thin layer of ice, making it a unique example of a "dead" lake. This isolation has preserved the lake's water, which is a deep red color due to the presence of high levels of iron and other minerals, creating an eerie and uninviting environment.
