8900-year-old wood found in Lake Huron

DETROIT (AP) - Researchers from the University of Michigan have recovered of a pole-shaped piece of wood that's 8,900 years old about 100 feet below the surface of Lake Huron.

John O'Shea, a University of Michigan anthropology professor involved in the find, says it offers hope that more intact evidence of human activity will be found in the area.

The wood is tapered and beveled on one side in a way that researchers say appears deliberate. It was found in July near the Alpena-Amberley Ridge, a now-underwater connection across Lake Huron that once linked the area of northern Michigan with Ontario.

The wood is undergoing more detailed analyses to determine whether its shape is due to human modification, which visual examination suggests.

More searches are planned.
