| Description |
Dr. Howard returns as Dr. Harbaugh's guest. With a model of a valley and synthetic ice, they simulate two types of glaciers in order to show the geologic work done by flowing ice. They point out areas on the Earth's surface where glaciers are at work today and show evidence of glacial work in the geologic past that has profoundly altered the whole geography of the North American continent as well as many other areas in the world.
