Descriptions:
At the end of the last ice age, geological fingerprints recorded in ocean sediments suggests glacier retreat of 50 meters a day, 18 km a year. For comparison the fastest retreating glaciers in Antarctica today are the Pope, and the Smith glacier system, retreating about 2.9 km a year.
