Iceland - Vatnajökull Glacier

Vatnajökull Glacier is 8100 square kilometres and is the largest glacier in Iceland (and 2nd largest in the world). This glacier covers active volcanoes and is inherently unstable. When a volcano erupts, the glacier melts and brings vast quantities of mud, rock and icebergs across the plains. You can see what one such eruption did to the massive Skeiöra Bridge.
