If you are a small town in Switzerland, what do you do if the nearby tourist attraction starts to melt?
You cover it with blankets.
Located in the Urne Alps near the town of Gletsch, the Rhône Glacier is the largest in the area. It also has an unusual feature that attracts tourists.
"You can go inside the glacier and see the different layers of ice. In a way, it is a bit like travelling through time," said Pierrette Rey of the Swiss branch of World Wildlife Federation.
