Here's what I grabbed from the few photos of the hole you posted,
The DOI was used with the codes so a person from the Philly area can be informed to pick up the goods once they were stored in the vault.
Ken Bauman also has found info that shows Philly is involved as a hub for their operations, or a place where some affair related to the Beale was planned...
When I used your DOI, the location and the clues died at a small lake....where the ARK and FE and the Fancy U were drawn into the ground......the letters POE can also be seen crafted around the pond...
Using your information it was impossible to get to the vault I found...
Some of the stones you have found with markings, the TJB, the Masons X, the letters ARK, FE and the Fancy U, also may correlate to the locations that are marked on the Map Stones as a large X. There are a few of them to chart, that's why I had originally wanted to team up...
Ken Bauman's theory also shows this location being in Philly and I believe he has located the area and building the DOI was delivered to in 1832, and is interesting to talk with him about these facts. It shows the larger operation was being plotted from higher ups, who might have been in the lodges in more than just VA.
What I found unique is the fact you located something with a minimal amount of info using the DOI, and the Beale Papers alone, and the fact that there are a couple of hunters being led to find the same area from other maps...
I believe this is a focal point of the investigation into this all.
Thanks again for talking with me about this...
Can talk to me anytime to clear any of the confusion up, or to confer with us on the whole, but just waiting to see your goods and solves....
