Scientists Solve Antarctica's Blood Falls Mystery After 112 Years
What Happened
In a breakthrough study published in 2023, Johns Hopkins University scientist Ken Livi used advanced electron microscopy to identify the final piece of Antarctica’s Blood Falls puzzle. The research revealed that nanospheres—iron-rich particles 100 times smaller than human blood cells—are responsible for the waterfall’s shocking crimson appearance.
These microscopic spheres form when ancient, iron-rich saltwater trapped beneath 400 meters of glacier ice comes into contact with oxygen-rich air. The instant oxidation process creates what appears to be fresh blood flowing from the glacier, but is actually an extraordinary chemical reaction millions of years in the making.
