You think they were trying to take measurements of the areas sub strata

LOL
Every ten feet, must mean that its natural right?.....that's my favorite excuse for not finding anything,
there are actually guys with degrees saying they have evidence to show that mother nature laid evenly spaced and cut timbers every 10 feet, in a perfectly square hole.......
and the comment and video posted a while back about the mystery that seems to take the cake, the one that claimed it was a Viking Ship that sank and the Mast became the water funnel tubes, after a mini ice age was even better
the side tunnels were very small and I doubt there was a person inside building them, they probably came at them from the top after building the dam, and held the waters back.......
the one channel that splits was created with double layered stones and another level of a particular blue clay they said, and the other side channels were dug to other area as well, they were designed to flood the main hole when the pressure from the levels of earth and the walls reinforcing the sides were removed, as was the numerous levels of clay and mud and wooden boards that held the pressure down from flooding
imagine putting two straws into a coke can at the bottom, and then trying to press air into the can through the straws. cant be done unless you open the top of the can.
so when all the clay and boards were removed, it opened the top of the can so to say, and the water filled from underneath, further "convincing" them they were onto something.
what they dont realize is there are tales told about other locations of side tunnels having been dug, the history talks about three side shafts, while most people only hear about two, if they dont seal off all the side tunnels they will be filling up holes with water and sinking their drills into soggy mud
and the crew there is digging for a specific Halifax shaft, to lead to the main money pit, to see if there is wood laid at a certain level...they are pulling out a core of wood from really deep in the next episode,
the 10x borehole pit at the bottom nearby, mayhave a chamber from an old mine from the time of that pyrite guys diggings but I looked up his history and is says his digging came from an area at the Eastern Most tip of New Foundland, not really even close enough to speculate it was him IMO
anyways you look at it they are throwing out all the options instead of looking for the best and earliest facts, which by coin dates seem to be spanish
