Mysterious Treasure on Oak IslandIn 1795, on Oak Island in Nova Scotia, three young men stumbled upon a round depression in the ground.

They dug down 30 feet before stopping. Every 10 feet they found a wood slat platform. As men, they continued the journey to no avail.

Over the years, millions of dollars have been spent to find the mystery at the bottom of the pit. 6 men have died trying to get to a treasure that may or not be there.

Still in 2010, no one has been able to get to the bottom, but it is said the owners of the island are waiting for a permit to start digging again.

This is very interesting and was mentioned on the show, "Ancient Aliens." Many think there's a treasure buried from pirates to be found.

Some think the "Ark of the Covenant" will be found, and others believe the pit is the final resting place of the "Holy Grail."
