Nigardsbreen, Norway/Glaciers

Glaciers are like gigantic planing machines. They wear away an average of two to three metres of rock every thousand years. The valleys created in the process mostly have a U-shaped cross-section. The Nigardsbreen is one of the big glacial tongues that creep downhill from the Jostedalsbreen, the largest glacier on the European mainland. Since first being measured in 1899 its front has receded by more than two kilometres. (aerial view)
