Amazing Blood Waterfall in Antarctica

[Source]

Blood Falls is an outflow of an iron oxide-tainted plume of saltwater, flowing from the tongue of the Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica. The reddish deposit was found in 1911 by the Australian geologist Griffith Taylor, who first explored the valley that bears his name. The Antarctica pioneers first attributed the red color to red algae, but later it was proven to be due only to iron oxides. [Wiki]
