Blood Falls, Antarctica

As explained in Amusing Planet, Blood Falls in Antarctica is home to an ancient community of microbes who have lived off the minerals that lie beneath the ice and snow, evolving in isolation from other planetary life forms.

In 1911, geologist Griffith Taylor discovered the blood-red falls and theorized that the coloration was the result of algae. Later it was found that a saltwater lake rich in iron lies beneath the ice and feeds the falls.
