Do you know?

In the McMurdo Dry Valleys of Antarctica, there's a peculiar feature known as Blood Falls. Despite its name, the falls are not actually blood but rather iron-rich, hypersaline water flowing from beneath the Taylor Glacier. The iron in the water oxidizes upon contact with the air, giving it a distinctive red color resembling blood. Scientists believe that the source of this unusual flow is an ancient subglacial reservoir.
