The Piz Bernina (4048 meters) is the easternmost four-thousander in the Alps and at the same time, the only one in the Eastern Alps. A huge part of the summit structure collapsed below the summit of this mountain giant.
The tongue of the huge ice and stone avalanche is five kilometers long. The huge amounts of rock, which had mixed with glacier ice, rolled over a rocky edge into the depths and poured over the high valley of Val Roseg. The mountain range on the border between the Swiss canton of Graubünden and the Italian province of Lombardy is a legend among mountaineers. The massif has several secondary peaks, one of which is the Piz Scerscen (3970 meters), the direct southwestern neighbor of the Piz Bernina. The Bernina section of the Swiss Alpine Club SAC speaks of a landslide as it has a volume of more than a million cubic meters of rock. The area was searched with a helicopter to check whether people or buildings had been injured.
