Blood Falls is located in the eastern Antarctica and flows from Taylor Glacier into
Lake Bonney.
It flows along horizontally for 300ft then flows into a waterfall of around 60-80ft.
The falls were first discovered in 1911 by Thomas Taylor, an Australian who was part of the British Antarctica Expedition.
The cause of the red water was unknown until 2003 when samples of water were analyzed and it was found the water contained iron oxide which formed when ancient seawater was trapped under the glacier and came into contact with the air.
The seawater is home to bacteria that has adapted to the conditions of having no light, oxygen and limited nutrients. They survive by breaking down the sulfate and iron in the water.
