Howdy ygtrader,
Welcome to the nut house. You are correct, they proved nothing. These people come, and go, you will find many videos making the same claim, with nothing to show. Most have a team of "experts" none of which share the same "knowledge". They all end up in different places, all changing the clues to lead you there.
I enjoy watching them all. The Dutchman story is real, just told different by many book writers. Those historians base their expertise on their favorite books, most of which have their share of lies, and misinformation. Funny thing is that Holmes, and Roberts got the same directions as Mrs. Thomas, and Rhiney. You will have to follow your own thoughts instead of following some one else's.
The PSM's are also very real, and in my opinion lead to the same mine. They had been buried in the 1700's, are they Jesuit? I don't really know, but even Scott W. couldn't figure that out. So don't lose hope, it has not been uncovered yet. Geology, geology, geology won't get you there, Waltz was a miner who knew about geology, and knew where he left it. "No miner will find my mine"
