Ice front

The glacier tongue is the - often tongue-shaped - lower part of a glacier. Often traversed by radial crevasses, it forms the zone at which the ice melts.

When the end of a glacier lying on the sea, solve blocks on ice and icebergs float as it - the glaciers " calving ". If it still rocks are frozen, they fall upon melting of the iceberg as " dropstones " to the seafloor.

Retreating glaciers left in places of their widely spread moraines - more or less crescent- shaped hills that were formed in front of the glacier tongue. More remains of former glaciers are in addition to various types of moraines, other deposition and erosion forms such as glacial striations, U-shaped valleys or boulders. Chunks of ice that leaves a glacier during withdrawal, may form after melting so-called dead ice holes - small lakes which fill with clayey sediment later.

The glacier tongue is also the site of the glacier, at which the turbid glacial meltwater milk Bach emerges from under the glacier. Often it forms a glacier from which the water exits. Prior to the glacier tongue is the Sander. There, the ablated material is deposited by the glacier in a plane.
