Retreating Glacier (IMAGE)
Caption
In the course of the last 150 years glacier has retreated by around one kilometre. In its place granite rock remained behind, which was gradually recolonized by living organisms accompanied by soil development. Following the formation of new soil the first plants, such as mosses and grasses, were followed by bushes and, later, also by trees.
