In 1795, settler Daniel McGinnis discovered a curious depression in a forest clearing on Oak Island off the southeast coast of Nova Scotia. With the help of friends, he began to dig, hoping to find a rumoured trove of pirate treasure.
At a depth of 90 feet, McGinnis uncovered a stone slab with strange markings. After digging a few feet deeper, the shaft filled with seawater. As it turned out, a 500-foot horizontal tunnel connected the “money pit” to an ocean cove. Artifacts discovered in the 200 years since have only added to the mystery.
