ANTARCTICA (南極洲) is a very cold continent where you can find the South Pole (南極). Here you may see lots of glaciers, which are made of ice moving very slowing down a valley.
Usually they are white because they are made of ice, snow and water. But there is one that is red like blood! Scientists call it ‘Blood Falls’ (「血瀑布」). Why is there blood in the glacier? In fact it is not blood and there is nothing scary about it at all.
In the past, people speculated that the red ice was due to red algae. But now, we know that the glacier is red because of the iron oxides in it – similar to iron rust we see in daily life.
