Paleo-Indians: These early people are believed to have traveled to this continent from Asia, over the Bering Land Bridge and into Alaska. They made their way south through an ice-free corridor between two massive glaciers that covered much of Canada and the northern United States. They followed their prey across the U.S.: big game animals like musk ox and caribou, wooly mammoths and giant bison. They left a trail of well-crafted spear tips called fluted points in their wake. The Paleo-Indians spread throughout the country, and eventually arrived in Maine. Ecological change was rapid at the time; the tundra landscape that was left behind after the glacier receded was quickly becoming the more forested landscape we know today, and Paleo-Indians were undoubtedly affected by such rapid change. Archaeological evidence shows that they either died out or diminished significantly shortly after their arrival.
