University of Colorado: Ancient tool found in melting ice

Boulder, Colorado (AP) July 2010

Researchers say they’ve found a 10,000-year-old hunting weapon in melting ice near Yellowstone National Park.

The University of Colorado announced the discovery during late June. Research associate Craig Lee said the spear-like wooden dart had been frozen in an ice sheet for 10,000 years and became bowed as the ice melted. It’s made of birch and looks like a bent tree branch.

Lee says increased global temperatures are causing glaciers and ice fields to melt, releasing artifacts as well as plant material and animal carcasses.

Later this summer, Lee and student researchers plan to visit Glacier National Park in Montana. They’ll work with Indian tribes there to find and protect artifacts that may have been freed from melting ice.
