Antarctica appears to looks Llook like it’sike It’s bleeding. Scientists may have finally figured out the real reason.
The blood falls are the result of a complicated interaction in which overlying ice, underlying rock, and an ancient lake bed form a pretty unsettling natural display.
Here’s what you’ll learn when you read this story:
- Antarctica’s McMurdo Dry Valleys, among the most extreme landscapes on Earth, are home to Blood Falls, an ominous, bright-red waterfall.
- While previous studies indicate that its eye-catching color appears when oxygen reacts with iron left behind by ancient microbes, a new study unveils the geological processes behind its briny red flow.
- It turns out Blood Falls serves as a release valve for pressure created by glacial ice above, rock below, and the nearby waters of briny, ice-capped Lake Bonney.
