Thousands of years ago, as the great glaciers began to recede, giant animals such as the woolly mammoth and mastodon roamed the area now known as Maine. Then, they were suddenly extinct.
Theories are many, but there are few clues.
One clue that does exist, however, is a woolly mammoth tusk that was accidentally found in 1959 in Scarborough. Perhaps some pieces of the puzzle can be found within the core of this ancient ivory. Adapted from the award winning Quest series, an added animated segment briefly explains the last glacial period in Maine. Your E-mail comments are welcome.
