Oak Island Money Pit

Was it pirates?  American  Loyalists?  The Knights Templar?  Theories abound about the origins of the infamous Oak Island Money Pit.  Located on an island off the coast of Nova Scotia, Canada, the Money Pit has been captivating and frustrating treasure seekers since 1795.  From individual diggers to full fledge excavation companies, each treasure hunter has been unable to find the bottom of the pit, let alone the treasure.  At each supposed success, the hole inevitably fills with sea water.  Is this a passageway to countless fortune or a natural sinkhole with nothing but mud at the bottom?
