Being one of the least inhabited places in the world, Antarctica covers about 98 percent of the area with ice. The average thickness is about 1.9 kilometer (6,200 feet). Adding to its wilderness, it is also home to a strange behavior: Blood falls. These are falls that pours out red colored water from the end of a glacier into lake.


 

It is a five-storey high outflow of blood colored water from the Taylor Glacier into the Lake Bonney. Australian geologist Griffith Taylor was the first to notice this phenomenon when he explored the valley. The glacier was named after him. 

The geologists first thought that the strange colored falls were the result of red algae but it was later proved wrong. The source to this blood colored water is about 400 meters under the glacier. The water emerges at the Falls through small fissures present in the ice cascades. 

The sub-glacial pool has high concentrations of salt, sulfate and ferrous ions. It is completely isolated from outer atmosphere and so when it comes into contact with atmospheric oxygen, the ferrous ions become ferric oxide giving the water red color.
