Ever heard of Blood Falls? It’s freezing cold, far away and hard to reach — probably not where you’re headed on your family vacation this summer.
Blood Falls is at the tip of a giant glacier in Antarctica. As its name suggests, the icy face of Blood Falls is red — but not from blood. Instead the water gets its hue because it’s rich in iron. When the water trickles out from its underground beginnings, the iron is exposed to oxygen in the air and quickly forms the red rust.
