One of the most amazing sights in Antarctica, the Blood Falls have been a mystery ever since they were discovered, in 1911.
A bloody column of water coming out of a glacier isn’t what you’d expect to see in the frozen land of Antarctica, but if you visit Taylor Glacier, that’s exactly what you’re going to find. At first, scientists thought they were dealing with some sorts of red algae, but further research proved the bloody color was caused by something spectacular.
It turns out a small lake was sealed under Taylor Glacier roughly 2 million years ago. Incredible, isn’t it?!? Actually no, what’s incredible is the glacier acted like a natural time capsule for the ancient microbes living in the lake. These invisible forms of life have survived without oxygen, light or heat and are considered to be the “primordial ooze” out which every living thing on Earth evolved.
The Blood Falls are proof life can be found in the most extreme environments, probably even on other planets, like Mars.
