The Rhône Glacier is a glacier in the Swiss Alps and the source of the river Rhône and one of the primary contributors to Lake Geneva. The glacier is located on the northernmost part of the canton of Valais, between the Grimsel Pass and the Furka Pass and is part of the Oberwald municipality. The Dammastock (3,630 m) is the highest summit above the glacier. During most of the past 11,000 years it was smaller than it is now. It is covered each summer in white blankets to try to slow down ice loss.
