The Blood Falls: Antarctica’s Creepy Crimson Waterfall

In the remote and icy region of Antarctica’s McMurdo Dry Valleys, there exists a fascinating natural wonder known as the Blood Falls. This fascinating site gets its name from its eerie resemblance to a flowing stream of blood against the backdrop of the snowy landscape. And it comes as no surprise that over the years, scientists and travelers alike have been captivated by these crimson-red waters. Truth be told, it’s not too hard to understand why. Especially if you’re someone who likes exploring unusual and quirky places. So, before you book your trip to Antarctica, here’s everything you need to know about Blood Falls.

Discovery and Early Guesses

Imagine how terrifying it must have been to discover this waterfall, right? And what makes it even more unsettling is the fact that this didn’t happen all that long ago. In 1911, Australian geologist Griffith Taylor came across this unusual sight during the Robert Falcon Scott’s Terra Nova Expedition. Because Griffith was an experienced adventurer, his initial instinct wasn’t to panic. Instead, the vivid red stream that was pouring from Taylor Glacier into Lake Bonney captivated his imagination. He couldn’t help but wonder what caused the unusual color of the water.

So, What Makes the Water Red?

Not too long after the discovery, the two World Wars would happen. Which put a pause on the investigation of Blood Falls. However, scientists would re-open the investigation in the 1960s in an effort to understand this phenomenon better. They conducted experiments where they traced the movement of water underneath the glacier by injecting colored dye into it. These experiments revealed something surprising: the water feeding the Blood Falls comes from a hidden lake trapped under the Taylor Glacier, called Lake Bonney Subglacial Lake.

Further research showed that the water from this lake is incredibly salty and contains a lot of iron. When this iron-rich water reaches the surface and meets the oxygen in the air, it rusts, forming iron oxide. This rust is what gives the water its deep red color, creating the eerie spectacle of the Blood Falls. The iron, combined with the high salt percentage of the lake’s water is also what helps the water of the Blood Falls not freeze.

What It Means for Science

What makes the Blood Falls truly remarkable is that they also helped us understand the ecosystem of Antarctica a lot better. It’s no secret that this is the home to some of Earth’s most extreme environments, which gives us a window into what life might be like in similar places elsewhere. Scientists have found microbial communities living in Lake Bonney Subglacial Lake, despite the harsh conditions of total darkness, freezing temperatures, and high salt levels.

Studying these microbes helps scientists understand the limits of life in extreme conditions. These findings also have implications for astrobiology, the study of life beyond Earth. By understanding how life survives in the harsh conditions of Antarctica, scientists can better imagine where else life might exist in our solar system and beyond.
