남극에 있는 피의 폭포

치질 아니고요.

남극 호수에 염분이 높고 iron이 많아서 산화 되면 저 색이 된다고 합니다.

Blood Falls is a striking, five-story red waterfall flowing from the Taylor Glacier in Antarctica’s McMurdo Dry Valleys. The red color is caused by iron-rich, hypersaline water from a subglacial pool oxidizing upon contact with air. The water is 3 times saltier than seawater and remains liquid despite being surrounded by cold ice (-17°C).
