Silvaplana Lake, Engadin valley, Switzerland. The valley is famous for its alpine lakes that are completely frozen in winter. Both Friedrich Nietzsche and Hermann Hesse report of their fascinating landscape on their writings. A lot of folkloristic events take place on their ice and a lot of people come to the valley for sport activities, or tourism. In recent years, temperatures have been higher and snowfall lower and the ice period has been shorter than usual. This factors cause environment impacts. Furthermore, the realization of these folk events could be at risk due to the unstable condition of the lakes.
