Blood Falls

There are many strange geological formations in Antarctica. Researchers have discovered a number of natural formations that are exclusive to the continent in recent years as the ice cover melts as a result of rising temperatures. But Blood Falls is probably the most shocking of them all.

Blood Falls are exactly what you're imagining them to be: a natural creation that resembles a waterfall of blood. They're found in a glacier called the Taylor Glacier. Although that might seem strange, the explanation is stranger. According to studies, the color is produced by bacteria that break down organic debris and transform ferric iron into its soluble form in an ancient lake that is buried beneath the glacier. They belong to a distinct, little-understood class of creatures that depend on sulfates for survival instead of oxygen since they had to develop in an environment without any light or oxygen.
