This eerie and mysterious blood-red waterfall is located in remote Antarctica. The red color is partially the result of saltwater tainted with iron oxide, which turns red when it hits the air. A new study from researchers at the University of Alaska Fairbanks links the waterfall to a large source of salty water that may have been trapped under a glacier for more than one million years.
The water is so salty, they say, it's more like brine. Researchers found that brine travels 300 feet under Taylor Glacier, which is the coldest known glacier to have persistently flowing water, according to the study published in the Journal of Glaciology.
The real mystery of these falls is what lives in the water. Water samples contain almost no oxygen, but at least 17 different types of alien-like microbes have been identified slithering around in the blood-like water. Scientists surmise that they survive via a metabolic process never observed in nature that utilizes sulfate as a respiratory catalyst with ferric ions, metabolizing trace levels of ancient organic matter trapped underneath Antarctica's vast glaciers.
