Extent of glaciation in Puget Sound – Video

Animation shows the stages of ice advance and retreat beginning 20,000 years ago. Fascinating YouTube video.

The tip of the ice sheet advanced about 450 feet (135 meters) per year.

Make sure to expand the video for the full effect. That also makes it a lot easier to read the explanations on the right side of the screen.

The Burke Museum in Seattle published this video on May 16, 2012.
