The research revealed that nanospheres—iron-rich particles 100 times smaller than human blood cells—are responsible for the waterfall&rsquo;s shocking crimson appearance.</p> <p>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.</p>
