Don’t worry—there is no blood at Blood Falls!Blood Falls, Antarctica, is a natural landmark. It’s found at the end of Taylor Glacier, near Antarctica’s usually ice-free Dry Valleys.Blood Falls gets its name from the blood-red water trickling from the glacier. The water is red because of the presence of iron. The iron in Blood Falls’ water turns red as it oxidizes, or rusts, when it comes into contact with oxygen in the air.
