Synopsis

About 20,000 years ago, much of North America was covered by glaciers. As the glaciers receded, they scoured the landscape, leaving behind basins that filled with freshwater. Kids will learn about glaciation and how the basins filled. They'll be surprised to learn the Great Lakes, which were carved by glaciers, hold about twenty percent of the world's freshwater.
