Sailing and Grailing Across the Atlantic

Current scholarship regards the map as being based on existing maps of the 16th century, in particular:

The Olaus Magnus map of the North, the Carta marina
The Caerte van Oostland of Cornelis Anthoniszoon
Claudius Clavus-type maps of the North
In the Money Pit on Oak Island, a mysterious stone inscription was found: "Forty feet below - two million punds are buried." Every company that has tried to locate this treasure has failed.

Oak Island is noted as the location of the so-called Money Pit, a site of numerous excavations to recover treasure believed by many to be buried there. However, the pit may have been a sinkhole or some other natural formation that was misinterpreted for centuries. The island is privately owned and advance permission is required for any visit.

Mid-19th century newspaper stories recount that in 1795, young Donald Daniel McInnis discovered a circular depression on the south eastern end of the island with an adjacent tree which had a tackle block on one of its overhanging branches. McInnis, with the help of friends John Smith and Anthony Vaughan, excavated the depression and discovered a layer of flagstones a few feet below. On the pit walls there were visible markings from a pick. As they dug down they discovered layers of logs at about every ten feet (3 m). They abandoned the excavation at 30 feet (10 m).
