Glaciers cover about 60% of Svalbard's land area with ice up to 600 meters thick. There are a total of 2100 large and small glaciers in the archipelago. Austfonna on the island of Nordauslandet is largest of them. It has an ice wall breaking into the Arctic ocean long, by different estimates, from 130 to 200 km. In the summer, the rivers and falls are formed of thawing ice on a glacier. They turn a fantastic picture into the absolutely surrealistic.
