These rocks on the highlands of the Andes looks like they are covered with moss. Actually, they are a type of flowing plant known as Yareta and it lives in colonies which can be thousands of years old.
It grows in the cold Puna grasslands of the Andes in Peru, Bolivia, northern Chile, and western Argentina at altitudes between 3,200 and 4,500 meters, where the wind blows unceasingly and the cold cracks even granite. To survive the extreme conditions, Yareta grows in packs so dense that its stems can take the weight of a human.
