11 of the World’s Most Otherworldly Landscapes

The earth is a strange and wondrous place, where natural occurrences are sometimes so odd they seem almost alien. Here are 11 natural formations that can be found on earth, but are out of this world.

Blood Falls, Antarctica

The grisly formation known as Blood Falls,  where red, blood-like water trickles out of an Antarctic glacier is a delightfully gory and natural phenomenon. The salty groundwater is rich in microbes, full of iron (which rusts when exposed to oxygen) and is thought to be at least 2 million years old. Scientists say the landscape is similar to that of Mars and wonder if it could hold the key to discovering more about life on the red planet.
