Definitions for "Deglaciation"
Disappearance by melting of ice covering an area. Deglaciation can vary greatly in speed, and ranges in nature from the retreat of a melting ice margin to the downward melting and fragmentation of stagnant ice.
When glacial ice receeds, the massive weight and movement of the ice resculps the ground. The terrain at DcRu4 is directly related to this type of process.
Uncovering of the land surface brought about by the melting of glacier ice.
