Antarctica Has a Blood-Red Waterfall

At the edge of the Taylor Glacier, red water seeps out, looking like blood—but it’s actually iron-rich brine.

In one of the coldest, driest places on Earth, a waterfall flows the color of blood. Known as Blood Falls, it oozes from the Taylor Glacier in Antarctica.

The eerie color comes from iron-rich, oxygen-free water that oxidizes when it hits the air—essentially rusting on contact. It’s one of the planet’s strangest and most haunting natural wonders.
