Google AI says...So here is where im coming from...
It seems to me that the MP would need to stay open until most if not all of the tunnel network is complete. Since it took 2 or 3 years as you estimated, than the shaft would be exposed to the rain and winter.
They could easily cover the MP shaft when it rained but the rain would still permeate down raising the water table and causing catastrophic issues.
Then you still have the catastrophic issues during the harsh winters on oak island. So how did they deal with that?
A cover over an unsupported deep vertical shaft is unlikely to prevent it from collapsing under 3.8 to 6 inches of rain. While a cover prevents direct rain from entering the hole, it does not stop the saturation of the surrounding soil, which is the primary cause of collapse.
So to prevent a cave ins, the shaft would have to be filled...
