Glacial striation. View over the striated (grooved) surface of bedrock in front of the Aletsch Glacier, Switzerland. These grooves were formed as the glacier passed over the rock, and debris frozen into its base gouged and scratched the surface. The Aletsch Glacier is the largest glacier in the Alps, with a length of around 23km and covering more than 120 square kilometres. It lies in the eastern Bernese Alps, Valais, Switzerland.
