even the best of the best can be wrong..do you know if they took samples from the river? that's where I found an issue. the sample taken in front of T bar is very similar to layer B of Palmers conclusion. and the clay type soil can be found upstream around Hayden Island..Tom Kaye believes he found a layer that runs the length of the beach vs a dredge layer..
Once they finished spreading the sand I'm guessing the erosion process already started. it constantly washes the beach away. I found it odd that such a thick layer was present so many years later?
Not all layers erode equally. I would think compacted consolidated clay bearing layers would erode less quickly. Uncompacted sand would erode quickly. Uncompacted dredging material would be move easily. It's not a linear removal, layer to layer.
One key is Palmer pointing out "crossbedding" in layer B? Cross bedding represents multiple alluvial events over time.
Palmer identified his layers by "content". Lose sands, coarse sands, extraneous materials (nails cans etc) showing signs of deterioration = time, clay vs no clay, lumpy clay, consolidated clay, etc.
But nowhere does he even mention erosion or attach dates to each layer except indirectly. My point is: you can't understand or explain a sand bar without discussing (a) erosion, and (b) time! Sandbars including Tina Bar is an active place. Erosion and time dating is fundamental to any explanation. It would be like trying to explain the contents of an old unlabeled can without dating the can! The date and state of the contents of the can match the date of the can!
Tom and I both talked to a lot of people about Palmer's professional work his areas of expertise, professional papers, etc. In every case (in my research) people said Palmer was a leading expert on beach EROSION! He was asked to go to St Helens by the Govt as a "sediment erosion expert". Nowhere in the socalled Palmer report is the word "erosion" even mentioned. That sends up a red flag, imho. Erosion is probably central to the Ingram money story.
And when you consider fragments at three feet and bundles near the surface in a sub-surface cross-bedded layer, now you are forced to look at the "forces operative on that sand bar over time" - its inescapable! Palmer told us that Tina Bar was a "static scene". Well no, not in 4.5 billion years has it been static there!
