ANTARCTICA'S BLOOD FALLS | The Mystery That Has Puzzled Scientists For Over A Century

Blood Falls is a natural phenomenon where deep red liquid pours from Taylor Glacier, defying the freezing Antarctic climate. For over a century, observers have watched this deep red stream emerge from the snout of the glacier onto the frozen surface of West Lake Bonney. It defies the extreme cold where liquid water should not exist and ice should be solid, creating one of the most striking sights on the continent. Antarctica remains a place of intense geological mystery, and this site offers a rare window into how water persists under such harsh conditions. By examining the chemistry and pressure within the glacier, we can understand why this brine continues to flow year after year, refusing to freeze despite the sub-zero temperatures.
