Glacial Polish
Description
Glacial polish is a rocky surface that has undergone erosion by a glacier. On the site, it is composed of gneiss, hard massive rock resulting from the crystallization of quartz, feldspar and partially melted micas. Striations enable the sense of the movement of the rock debris set in the ice to be seen. In the fractured parts of the rock, fragments of rock have been pulled off by the ice. This phenomenon is called “sub-glacial cutting”.
