Black ice on the lakes of the Upper Engadine
It is a natural phenomenon that only happens very rarely. If there is no snowfall during the time when the Upper Engadine lakes freeze over, the surface becomes blank ice. It should be pointed out here that stepping on the ice or skating on the lake is always at your own risk.
The picture shows a panoramic view of about 200 degrees from the center of the black frozen Lake Sils.
The dominant mountain in the center of the picture is Piz Lagrev (3164m) on the north side of Lake Sils.
The picture shows an almost 360 degree panoramic view of the Lake Sils shortly after the sun went down.
