1918 Shipwreck at Niagara Falls Shifts, Nearing the Edge

A historic shipwreck at Niagara Falls is on the move. The iron barge, stranded just above the famous Horseshoe Falls in 1918, has shifted closer to the edge. Recent water and ice movements have carried it further from its original resting spot. The barge became famous after a dramatic rescue. In 1918, it broke loose while being towed. Two men were trapped aboard for 17 hours before rescuers in a lifeboat reached them. For over a century, the wreck sat mostly stable on the riverbed. Its new movement brings an uncertain future. Experts say it could eventually be swept over the falls.
