The Extreme Ice Survey has a collection of videos that document the retreat of numerous glaciers. These were produced by taking sequential photographs from the same location.
Be sure to point out that the advancing is done in winter and the retreating in summer. The retreating edge front line shows quite a dramatic change in just a few short years.
