Nova Scotia's Oak Island is for sale. Its price tag of $7 million may be worth the investment considering the island is home to the famous Money Pit.
The Pit was discovered in 1795 by a local boy named Daniel McGinnis who, spotting an unusual clearing in the earth under one of the island's oak trees, was prompted to start digging. The discovery of layered planks, mysterious stone slabs, and mats made of coconut fibers descending deep into the ground turned his casual afternoon dig into an all-out excavation.
What appears to be a complex flooding trap has thwarted efforts to reach the bottom of the Money Pit ever since. Some think the pit was purposely flooded with seawater, via a series of artificial swamps and tunnels, to hide its contents.
