Unless some other source can be shown which explains 'element-x' at Tina Bar, the one logical source is the 1974 dredging spoils pulled from a region known to contain element-x, those dredging spoils then deposited on Tina Bar in 1974
Why is Tom against the dredge theory if this is the logical source? I would believe this theory, but only if it can get past the pump. it is extremely logical, but can it become a fact?
I cant speak for Tom, but my feeling is (a) Tom didn't think the presence of element-x in his bill scans was unusual, (b) he didn't think the level of 'x' was significant enough to warrant further exploration, (c) he thought the USGS chemist's claims were either bogus or nonsense or wrong, (d) ... the horoscope for element-x was wrong!
Fact is, until I talked to the USGS chemist I saw nothing unusual about element-x in Tom's scans. It was the USGS chemist that raised a flag the moment I mentioned element-x.
Tom's claim was that there were no 1974 dredging sediments left six years later in 1980, on Tina Bar, to contaminate anything with. The USGS chemist wasn't sure about that claim.
The chemist suggested that wood, trees, and other artifacts at Tina Bar be tested for element-x and compared with similar artifacts from other beaches on the Columbia - as a control. He suggested that some lab work should also be done to establish a dose-response timeline for exposure to element-x; he said the USGS had already done some studies and he would get that info to me ....
A primary question we were tasked to answer was "when" the money had arrived on Tina Bar. Contamination levels might help answer that, but the work was not completed ... Tom didn't think the presence of element-x was significant and he had other priorities. Frankly, I was being intimidated from every possible angle and I (and others) finally just said "Fuck it!" and I dropped the whole thing to wait for Tom's work to be completed. Later, I set up a second round of testing using Brian Ingram bills but word of that leaked out and that was shot down also! Ingram abruptly cancelled delivering money specimens to us! (People waiting in labs were really pissed and at that point we literally gave up on this whole fiasco ...everything had become political.) Those are the facts.
It had taken me weeks to set up a second round of testing using named people in labs across America. The testing scheduled was going to be far above anything Tom Kaye is even capable of doing. What I arranged was a kind of 'cooperative of testing' where everyone results were going to be shared, universally. I thought we stood a pretty good chance of providing brand new information about the money, hopefully answering a few basic questions, and perhaps scoring a breakthrough. I was basically going to finally do the testing I had originally wanted to do vs turning things over to Tom Kaye alone (which is what Larry Carr did).
My arguement/arrangement with Brian Ingram was very simple: I told him we would cover all costs, we would provide him with signed copies of all tests done, and I told him that by the end of this he would have a very unique package of information to go along with his bills ... and that it was my feeling all of that would raise the value of his bills at auction. Everyone signed up to do the lab testing had agreed to this premise. I clearly understood Brian's interests were economic, while our interests were pure research and documentation trying to gain some hard information in the DB Cooper case, something that would help the FBI. In the end, Brian nixed the whole thing. Tom was left to do his work, book writers were left to write their books, ... and I and others just 'called it a day' in this whole enterprise. It's kind of funny when you think about it. C'est la vie.
