The main picture is showing the Lago Bianco (see also PiP) and the road across the Bernina Pass before reaching the highest point. I took this picture from the Diavolezza cable car.

The Bernina Pass (2.328 m) is a mountain pass in the Bernina Range of the Alps. It connects the famous resort town of St. Moritz in the Upper Engadin valley with the Italian-speaking Val Poschiavo, which ends in the Italian town. Old paths crossed the Bernina Alps for hundred of years from Grisons to Valtellina in Italy. Back in 1865 a modern road replaced the old paths, which has been widened a number of times and has been open 365 days a year since 1965.

The Bernina Pass is also crossed by rail. The world famous Bernina Express has been travelling over the pass in summer since 1910 and since 1913 this popular tourist train is operating year-round between Chur and Tirano. It is the highest adhesion railway route in Europe. Energy source for the train line is the Lago Bianco, a hydro storage lake.
