Understanding how its done can help find it
I will start by saying I am a huge fan of this show. I am a "Driller" by trade for the past 33 years. I have noticed a few mistakes over the past few seasons, but am impressed with the drive and passion put out by the crew. I realize time and money rule in this world so I understand the path that has been taken to get this far.
I'll bet every viewer of " Oak island " would greatly appreciate an episode that goes into detail of how such a tunnel and or shaft could be constructed. How is it even possible to get that deep on an island? WHY? If the soil on the island is highly cohesive, sure a tunnel would be easy to construct. Surely they were not digging for silver or gold in silt material...That means a tunnel was constructed for the sole purpose of hiding something.
One end of the island has a possible entrance to a tunnel. This could have been the start to a 45 degree decline in the ground. The cohesive material would be relatively easy to keep open. the problem lies in the ground water. How do you keep it from flooding the tunnel? Was the shaft possible a vent shaft? So many unanswered questions. What technology was available over 400 years ago that could enable such a venture? Just how in the world could a box drain be constructed and made into a water trap? Answer these questions and you may be a little closer to the actual treasure.
"Witching" , a means of locating underground water , is a lost art but one that could prove very valuable to this endeavor. I am not sure if this technique has been employed but it could very well locate a buried box drain or existing tunnel?! A lost art indeed but i'll bet there are a few old timers that would love to locate some anomalies for the cause.
PS. Old guys work for cheap, they usually have their own witchy sticks too.
I agree with you on that. How was it done? Even if ocean levels were lower hundreds of years ago that wouldnt have helped a lot. Static water levels would be pretty much whatever the ocean levels were so how exactly would a shaft or tunnel be dug much beyond the 90 ft that the water levels were hundreds of years ago?
Additionally I believe that there is limestone down there which could account for "caverns" or "voids" one such as indicated at the bottom of 10X. The diver said it appeared to be natural, not man made. Limestone dissolves over time in water so limestone could account for the empty spaces.
So many things dont make sense to most people who have dealt with realities encountered in excavations etc. If oak island was a huge rock with dirt on top of it I might better understand how 200-300 years ago earlier people could have dug a shaft straight down 200 ft or more into solid rock but from what I have seen dirt is encountered in most drilling operations going down 200 ft.......Dirt is NOT going to hold the ocean back so how did they do it 2-300 years ago?
Surely though, why would someone bury a book or manuscript so deep below ground that had to be extremely damp or even below water? Makes no sense to me.
Talk about a mystery. Im more interested in the "how" of it almost that the "what" is down there.
