Has an agreement every been verified as to how far the dredge material was spread. this is a good distance away to have that much material.
The figure quoted in our FBI docs is '50 yards both directions from center' of each spoil mound. That is the reason Tom says the Ingram find can't be from the dredging. If you double that to 100 yds to allow for post dredging movement due to settling and water pressure in the direction of flow, now you are approaching site "B" where fragments were found. You might be able to close the gap further by introducing more movement north, due to high water events 1975-80.
We dont have a working model of sediment movement! We dont have photos showing an object being moved northward from 1970-80 or from 74-80. Nobody has even tried to address the issue of movement even though it definitely occurs ... in the direction of current flow, north! All we know is the Ingram find is north of the 74 dredging spoil, in the same direction as flow pressure.
Keep in mind Tom believes the Cooper money got deposited at TBar in 71! He never has explained how.
We have no lab work dating any strata!!
I think Palmer was under great pressure from Himmelsbach to build a story consistent with what Himmelsbach thought he knew! In doing that Palmer lost his scientific independence. You dont do science based on what some FBI guy is telling you what to think and do! Other agents questioned and disagreed with Himmelsbach's and Palmer interpretations. That is documented. One agent even suggested that ice brought the Ingram money onto Tina Bar.
