Yeah, G, where did it go? It was quite a comprehensive analysis of the soils at TB.
I didn't think anyone was interested. I may redo later and post it in the Tena Bar Money thread. Basically its an analysis of the Palmer report as it corresponds to Kaye's analysis.
Tom and others focus on the 'clay lump and sand' layer Palmer identified as being the dredge spoils from 1974. Above that layer, Palmer identifies a "cross bedded sand" layer which in the Palmer analysis may be the actual baseline against which he assigned all other strata. Each layer found represents a segment of time. The cross bedded layer would presumably represent all deposits, wave action, and erosion between Sept 1974 and the start of the 'upper active layer' which may start in 1978, after the severe drought of 1977. If Palmer is correct then the "cross bedded layer" can only correspond to water events between Sept 1974 and say Sept 1978. So the question arises: does the Columbia river height data at the Vancouver station between Sept 1974 and Sept 1978 support multiple cross-bedded deposition events (at Tina Bar) between Sept '74 and Sept '78, and generally I think it does. Palmer had access to those same Vancouver station records I do today. Those water event records seem to confirm the cross-bedded layer consisting of multiple high water events, which Palmer identified as layer "B". On that basis Palmer would be fully justified in claiming that the "clay lump and sand" layer "C" found
below the cross bedded sands layer "B", was in fact the dredging sediments from 1974. Then on top of Layer "B" Palmer places the "upper active" layer representing deposits from say Sept 1978 to the current time February of 1980 - and it is in this topmost layer "A" the Ingram money was recovered.
Kaye arrives in 2008 and finds a severely eroded beachfront at Tina bar, Kay can see a clay layer exposed in the erosion cut, and Kaye believes that clay layer he is seeing predates 1974. Tom believes this is the very layer Palmer was looking at in 1980 and called the 'dredge spoils' layer, but it was not. Tom may be saying that the dredge spoils layer had all but washed away by 1980 and so there was no dredging layer to be found, and Palmer misidentified a deeper (pre 1971?) layer as being the 1974 dredge spoils 'clay and sand'. Quite frankly, it is difficult for me to believe Palmer would make such a basic mistake. Palmer was an expert in this area.
Tom would then assign Palmer's cross bedded sands layer 'C' as consisting of (a) remnants of the dredging spoils deposited in 1974
and post 1974-Sept 1978 sands laid down by multiple water events between the end of 1974 to say early 1978.
All of this matters because the dating of the layer in which Ingram money was found is crucial. The water records must agree with the strata found, in any event. And the Vancouver station records I have generally support the multiple water-deposition events which Palmer's cross bedded sands layer 'B' implies.
I can easily see how Palmer would have identified anything below layer 'B', especially anything containing clay, as the 1974 bottom dredging sediments which consists of both clay and coarse sand. But, the baseline is set in Palmer's mind once he see's the cross bedded layer 'B'. Stratum 'B' represents a definable period of time against which actual nearby river station records can be checked. Please recall, it was not just Palmer out a Tina Bar alone. He had backup and co-researchers working with him, some of who are named on Kaye's site. (a professional hydrologist for one).
So Palmer is not operating in complete darkness here.
Do water-weather records support the idea that all of the 1974 dredging spoils placed at Tina Bar had withered down to a non-existent thin layer by the time the cross bedded layer 'B' starts to be assembled at Tina Bar? No. There is nothing to support that contention. The best one could do is contend that cross bedded layer 'B' represents a portion of dredging spoils
and post-dredging sands laid down between 8-74 and say 9-78 when we are sure the next cycle of deposition with the flood of 1978 begins (and deposits the upper active layer Palmer found).
This exercise illustrates the issues involved. But, water and weather records must correspond and account for whatever beach strata are found, because beach's just don't build themselves!. Beaches are a temporal story of deposition, erosion, water and wave action, et cetera. Beaches are a clock.
