Daniel McGinnis discovered a mysterious depression on Oak Island off the coast of Nova Scotia in 1795. He and some friends dug down 30 feet until they were forced to stop, beginning the long mystery of what lies buried in the island's "money pit". Subsequent excavation attempts discovered different layers of materials and artifacts, including an ax and scissors. Modern excavations using cameras and digging technology have found tools, chests and human remains, but the pit continues to flood, preventing access to its secrets. To this day the origin and contents of the Oak Island money pit remain unknown.
