Blood Falls of Antarctica

Flowing out of the Taylor Glacier in Antarctica’s McMurdo Dry Valleys is a five-story waterfall that looks exactly like a continuous stream of blood. Discovered by a geologist in 1911, the crimson color actually comes from an ancient, iron-rich subglacial lake that has been trapped beneath the ice for nearly two million years. As the iron-heavy saltwater finally seeps through the cracks in the glacier and hits the freezing, oxygenated air, it instantly rusts, creating the terrifying, deep-red stain against the pristine white ice. It is a chilling yet fascinating reminder of the bizarre extremes hidden on our planet.
