Some pieces in collections have left a trail of mystery

Several years ago, a longtime Concord resident was taking a walk along the banks of the Sudbury River with his granddaughter when the little girl tripped over a peculiar relic. It was a spearhead dating from the presence of Native American tribes approximately 10,000 years ago, by the estimate of local historians.

Today the sharp-edged stone is part of the permanent collection at the Concord Museum, whose director, Emer McCourt, remains fascinated with the slender artifact. Simple as the spearhead is in terms of construction and use, McCourt cannot help but puzzle over one basic question: How did it sit on a riverbank for 100 centuries before being discovered?
