I was just browsing, wondering what a Kitty Dump is, and didn’t quite expect to find this particular topic on a CAD forum!
I’ve been researching the Oak Island mystery for some forty-five years and have even written a book about it, suggesting that the deposit, had there been one, was surely unlikely to have been in the Money Pit.
For one thing, by all accounts, this was made particularly obvious at the centre of a clearing and marked by a conspicuous tree having a tackle-block suspended from a bough above the pit inviting all and sundry to “Dig Here”. So, this definitely wasn’t a concealment!
It’s also possible that with the collapse of the pit anything placed therein will have been widely dispersed. In fact, such a mess has been made of the area surrounding the Money Pit it would really have to be hoped that any deposit on the island wasn’t put there.
My suggestion is that the eastern ground markers (essentially the Money Pit, the two drilled rocks and the two triangles) are potentially inter-connected by a geometrical plan that when exposed identifies a very obvious focal point to the northeast of the Money Pit. The Money Pit is assuredly a point that has to be known about, but seems not to be a spot that you have to bother with.
To illustrate the suggested ground plan, I used 2D CAD to overlay drawings on imported images and aerial photographs and dropped them as GIF and JPG files. Thus, I could effectively plot a suggested survey schema that allowed me to rapidly determine distances and bearings between points on the ground thus taking all the hard work out of the many calculations involved.
In case anybody is interested in what this ends up looking like, I include below an image from my book showing an example. This places the two drilled rocks and the triangles exactly in accordance with the findings of the Roper Survey conducted in 1937. The point is that having determined how these ground markers relate to each other, the five sets of instructions on the much disparaged maps that are associated with the island begin to make perfect sense. That is, they all work in exactly the same way.
Oak Island: Potential Geometrical Overlay
The line from P0 to P10 is in ten sections of 25 rods, at first following the line of the Roadway then extending beyond it. The potential reconstruction shown here is based on equilateral triangles, though it employs angles of 30 degrees as well as 60 degrees on both true and magnetic meridians.
Note well that giving rise to this possibility, and presumably intentionally left as a pointer to it, is that the Welling Triangle and the Mallon Triangle were both equilateral with sides of 10 feet. Thus, the angle of tilt of the Welling Triangle can be expressed as ArcTan(1/√75). This actually seems to be a pointer to the angle of magnetic variation being twice this at ArcTan(2/√75) = 13 degrees (NW). This again seems to have been intentionally left as a pointer which might argue that anyone wishing to recover the deposit has to know this angle.
So, maybe they’re not finding anything in the Money Pit area because they’re digging in the wrong place. However, does anybody listen? No!
