Advance and retreat of the Alpine glaciers during the last glacial cycle

About 25'000 years ago, Alpine Glaciers filled most of the valleys and even extended onto the plains. Using a computer model that contains knowledge on glacier physics based on modern observations of Greenland and Antarctica and laboratory experiments on ice, help from traces left by glaciers on the landscape, and one of the fastest computers in the world, this animation is an attempt to reconstruct of the evolution of Alpine Glaciers in time from 120'000 years ago to today.Author:Julien Seguinot (2018)Reference:J.
