Oak Island Mystery

A man named Robert Dunfield started his search for treasure on Oak Island with bulldozers and cranes. He dug 140 feet down the pit to the thick layer of limestone. Daniel C. Blankenship started his investigation in 1965. At 60 feet, he discovered a hand-wrought nail and a washer. He even found a wrought iron scissor, which dates back to 300 years and was made in Mexico.
