This illustration depicts North American glaciation during the ice age. The Laurentide Ice Sheet was a sheet of ice covering millions of square kilometres of modern-day Canada and the northern United States from 2.5 million to 20, 000 years ago. It was the main feature of the Pleistocene epoch in North America. During the same period, the Cordilleran Ice Sheet covered areas west of the Continental Divide. | |
