13,800-year-old Alaska campsite sheds light on early Americans

Researchers studying the Shég' Xdaltth'í' site in Alaska have uncovered a camp dating back about 13,800 years, with stone tools, animal remains, a hearth and signs of a possible shelter. Evidence points to food processing, toolmaking and clothing production. Similar tools found in Siberia suggest cultural links across the ancient Bering Land Bridge.
