Switzerland. Canton Valais. Oberwald. The Rhône Glacier. In order to prevent melting ice from the Glacier due to sun and global warming, men have installed large white tarpaulins over the 100-metre long blue ice tunnel and ice chamber, which have been cut new into the Rhone glacier every year since around 1870. The Rhône Glacier is a glacier in the Swiss Alps and the source of the river Rhône. Because the Glacier is located close to the Furka Pass road it is easily accessible to local and foreign tourists. View on the Tieralplistock (3,383 m) at the end of the Glacier. 24.07.2016 © 2016 Didier Ruef
