Blood Falls

Download Article

Antarctica’s rare blood-red waterfall isn’t actually made of blood. Instead, it appears as a rare crimson color because the lake it comes from has been preserved under salty ice for years. The lake is rich in iron, too salty to freeze, and has no oxygen. When the iron-rich water comes in contact with the oxygen in the air, it rusts, creating a disturbingly beautiful red color.^{[22]

- Blood Falls can only be reached by helicopter from nearby Antarctica research stations or cruise ships visiting the nearby sea.
