this explanation appears to me to at least account for some of the anomalies involved. The premise regarding the Flood Tunnels, etc seems to be based on a long line of hearsay and assumption. at least this theory has some credibility and factual basis.
Great theory presented about the alleged flood tunnels, but there is way more to the geology of Oak Island than meets the eye.
According to those who have studied it, Graham Harris and Les MacPhie included, the geology of Oak Island does not allow for natural ingress of salt water into the core of Oak Island, certainly not in the first 150 + years of treasure hunting on the island.
The existence of the flood tunnel has been put to bed a long time ago and only the most ardent skeptic like Joltes allows himself to discount the fact that the flood tunnel (at least one) exists. Not only has Joltes not been to Oak Island and depends on the research of others who have taken the time to visit, but he does not give out all the facts so a neutral observer can make an informed, unbiased opinion. He presents a great argument, but in a debate, his pre conceived notions fall far from the line.
As for here say and assumption, one only needs to read the original correspondence by numerous treasure hunters who testify this feature not only exists but allows for a protection that has not been seen before in nay other treasure hunt, it is unique. It is in black and white and first person testimony is always strong evidence held by the highest levels of a democratic people . Generally, those who don’t accept this type of evidence are those who have a special interest in the weakening of a story.
There is no upheaval of bedrock on the eastern end of the island that would allow for natural inclusion of salt water in a fissure or opening to flood the Money Pit area. As you pointed out, the bedrock in that area is quite deep, too deep to allow for natural water inclusion.
It has become fairly and widely understood that the suspected flood tunnel from the south shore may in fact be a natural water course inlet due to the massive pumping that has occurred on Oak Island in the past fifty years or so. As anhydrite is not only soft and easily worked by the hand of man, but it is also water soluble, and tens of thousands of gallons of salt water roaring through what were once fissures, became larger water tunnels that bring in salt water from the bay.
It would be nice to discount 212 years of evidence gathering and results that have been discovered on Oak Island, but that is not the case. It can’t be summarily discounted and it cannot be ignored. It is easily misunderstood and discounted by many until they have conducted a reasonable search for good information, not some of the dribble we see on the internet in places that have no credibility.
As Andrew has set up a site all about Rennes Le Chateau and there is no one here who can really speak with accuracy about Oak Island, I invite you to register with www.oakislandtreasure.co.uk
for an informed discussion with people who understand the mystery of Oak Island in a relaxed and friendly atmosphere. I can guarantee you that you will not be subject to insults, debasing comments and random nonsense as you read here regularly in these threads.
