Red-colored seep of saltwater flowing from Taylor Glacier in Antarctica
Blood Falls, 2006Blood Falls, at the toe of Taylor Glacier, 2013
Blood Falls is an outflow of an iron oxide–tainted plume of saltwater, flowing from the tongue of 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.
Iron-rich hypersaline water sporadically emerges from small fissures in the ice cascades. The saltwater source is a subglacial pool of unknown size overlain by about 400 metres (1,300 ft) of ice several kilometers from its tiny outlet at Blood Falls.
The reddish deposit was found in 1911 by the Australian geologist Thomas Griffith Taylor, who first explored the valley that bears his name.[1] The Antarctica pioneers first attributed the red color to red algae, but later it was proven to be due to iron oxides.
