Lago Bianco, Bernina Pass at 2234 meters The Lago Bianco is a reservoir at the Bernina Pass and is located in the area of the municipalities of Pontresina and Poschiavo. The lake is located directly at the pass at 2234 meters above sea level. The Lago Bianco is bordered by two dams on its north and south sides and is around three kilometers long and about 800m wide. When filled to its maximum, the depth of the Lago Bianco is over 50 meters. The reservoir on the Bernina Pass is fed by various mountain streams and glacier water, while the Cavagliasch in particular leaves the lake. The whitish, somewhat milky-looking Lago Bianco gets its name (in German "White Lake") from the inflow of sand and glacier water. The Bernina Hospice (Ospizio Bernina) is located on the western shore of Lago Bianco, and the Rhaetian Railway's train line - the Bernina Express - also runs directly along the shore. The Bernina Pass road is also located on the western side, but not directly on the lake shore. In cold winters, the lake can freeze over and in some years the beautiful black ice forms. When the reservoir is then opened by the authorities, nothing stands in the way of ice skating on Lago Bianco. Text / Source: Schweizersee.ch https://www.schweizersee.ch/lago_bianco_pontresina/

The river originates northeast of the Lunghin Pass in the Swiss Upper Engadine at an altitude of 2,564 meters above Lake Lunghin. The pass above the source is a major European watershed point (North Sea, Black Sea, Adriatic Sea). Inn in the Lower Engadine between Susch and Lavin (2008) Until its confluence with the larger Flaz, the Inn (En) is also called the Sela and initially flows through Lake Sils, Lake Silvaplana, Lake Champfèr, and Lake St. Moritz. The small Lake Gravatscha near the mouth of the Flaz is an important breeding ground for birds. In the Lower Engadine, the Inn flows through several gorges with a significantly steeper gradient.

After the cordoned-off part of the path (the view is beautiful) you pass under this suggestive rocky claw....then a steep zigzagging uphill section begins.....then take a breath and stop to enjoy the view (better in the afternoon with the sun reflecting on the lake)
