For over a century, the startling red waterfall known as Blood Falls, flowing from the Taylor Glacier in Antarctica, has puzzled scientists. The mystery of its color and source has now been fully explained. Researchers have determined that the water originates from a deep, ancient subglacial reservoir, trapped for potentially millions of years. The distinctive red color is not from blood or algae, but from iron-rich brine. When this iron-laden water emerges and contacts oxygen, it oxidizes, forming iron oxides that stain the ice a dramatic blood-red. This discovery concludes the long-standing investigation into one of Antarctica’s most visually striking phenomena.
