Oak island tunnel system depthed down about 100 feet from smiths cove to money pit but inland further than thought; new research explains oak island shore line receded over the centuries this information may help in how the money pit was created?
Oak Islands smiths coves first old ancient dam may have been a actual natural shore line rather than a man made dam at one time? And the money pit tunnel system exit may or has been in land further from the beach area borders at one time over the century's due to erosion of beach front.
Knowing how the oak island money pit worked is in understanding its geological past.
