Rocks the size of houses thunder on the road from a posh ski resort to Italy. The Engadine in the Swiss canton of Graubünden is one of the most beautiful valleys in the Alps.
In recent weeks there has been a sensational series of rock falls, particularly in the southern Alps. Most recently, a mountain road on Lake Garda was buried. And on neighboring Lake Ledro, a road was recently completely blocked by falling rocks. Many experts blame the changing climate for the strikingly high number of rocks.
