Georger, before I moved to Washington I was a commercial beachcleaner in New York. Over an eight-year period I cleaned a lot of debris off of beaches, and here is my humble opinion about Paul and his detritus.
I think the primary dynamic for debris wash up is the contour of the beach. I think the steeper the beach gets the less debris will be present. The currents simply wash stuff away.
In Paul's video, the strand is certainly very gentle. Further, the river does not appear to be too deep in the immediate areas just beyond the shoreline, and I saw a couple of tree stumps - root ball-types of wash-up - that were just sitting in the water. Also, the currents did not appear too strong in Paul's video. These are not the conditions of T-Bar.
But the whole scene had a feel for the Lower River Rd area of the Columbia, so I figure Paul was close to T-Bar, but still some distance away from the actual money-find spot.
Simply, T-Bar is NOT a junk magnet. But someplace else is, and where that is remains unknown. Paul could have been walking along the lower portions of the Lewis River at the confluence with the Columbia for all I know.
Lastly, after reconstructing the actual conditions at T-Bar as they existed in the 1978-1980 era, with a more gentle slope than now, I consider T-Bar as an unlikely place to accumulate wash-up before the money find. T-Bar is in the middle of a long run of unchanging beach contours.
Well the debris shown in Pauls video is somewhere?
Where?
And presumably that debris was not put wherever it is by some flying saucer! It washed in by natural means during some period of time.
Let's remember here that the last GPO printed topographical map for the Tina Bar area, I don't remember its date but I gave Meyer Louie a copy of it and perhaps he could check it out, called the area between Caterpillar Island and the mainland "mud flats". Also, there was a shipwreck indicated at the north end of CI.
Apparently somewhere in the 1970s, those mud flats were dredged so that boats with about a four or five foot draft could navigate the channel between CI and the mainland and the present marina was built in that channel. The wrecked ship was apparently removed about the same time. Amazon kept her boat there (and lived on it) for several years in that time frame. Perhaps she would be able and willing to give some precise dates here.
Further, and also in the 1970s, the Flushing Channel was built with its inlet to Vancouver Lake a short distance south (upstream) of CI. Perhaps the construction of the Flushing Channel, the dredging of the mud flats, and the shipwreck removal contributed to a change of river water flow patterns around CI and Tina Bar. My guess is that the water coming through the channel with the marina would constitute a "boundary layer" some distance downstream (to the north) of CI and past the Tina Bar money find location. This would reduce the amount of debris from the main river channel that ended up on the then gradually sloping beaches at Tina Bar. The "boundary layer" would keep the debris in the main river channel and away from the beach.
Its a straight shot from the CI channel on to Tina Bar and with high water, current, or even tides an object could then flow further down Tina Bar to the find site perhaps to be deposited there.
This still doesn't account for all the debris shown and the location in Paul's video.
The debris is the reason I was shocked by Paul's video. I am only assuming he is somewhere in the Tina Bar area. And, if you go back and look at old photos including excavation photos you don't see that kind of debris on Tina Bar. The only reference I have is a statement from JT who talked to the Fazio's saying a lot of debris collected on their beach during high water - for whatever that statement is worth? And of course JT's own claim that balls he released in the Washougal wound upon Tina Bar, a statement repeated by Givet in his video.
We know the flightpath crossed the Columbia River - somewhere! If Cooper landed in the Columbia basin then that increases the chance his money wound up at Tina Bar
by natural means. If some facts of hydrology favored the Fazio beach as a deposition site, that further increases the probability Cooper money could surface in the Tina Bar area,
by natural means.
