I don't know, perhaps there is a logical reason for so much sediment to build up on the beach. I don't think passing ships will have much impact on the beach. the ships mainly run through the center of the river. the wake would settle by the time it reached Tina Bar.

I can't see water levels dropping this much sediment? even over long periods. the Fazio's were there way before this happened. you would think they would know the river dumps tons of sediments on the beach?

What about the flood prior to 1980? I find records of the flood in the 90's, but nothing on the flood in 78/79?

I wonder what the Army Corps. would say about any of this. do think they have any answers?

My long post above saying I dont have the answer to your question. Your question 'is the question'! I think you are getting way ahead of the discussion?

Crop from Tom's photo ...

Does anyone know the exact location the picture above was take, can it be pinned on a map?

Is there a "volunteer" surveyor with a Differential-GPS who could take accurate readings on elevations and determine profiles between Tina Bar and the Flushing Channel (north/south) and the river and NW Lower River Road (east/west)?

I have never seen a surveyor type map for that area, and probably never will, but such would be exceedingly useful.

It would probably be north (downstream) of the money find location at Tina Bar.  That's assuming the picture was made in the last several years.

I think I might have some documents with elevations on them......let search my thumb drives. I think that's where they are....

Tom does - he took the photo. The photo is on his website. My guess is they are close-by. Tom says:

The eroded beach now clearly exposed several continuous layers of consolidated clay alternating with clean sand (Fig. 1). Measurements based on the level of the grass at the top of the beach and the exposed tree roots (Fig. 2) indicated that the now-exposed clay layers were at the same approximate depth as Palmer's original trench.

In fact this passage seems to answer my question in my post earlier, asking if strata in the Palmer trench and present day strata match. Tom seems to be saying they do: Measurements based on the level of the grass at the top of the beach and the exposed tree roots (Fig. 2) indicated that the now-exposed clay layers were at the same approximate depth as Palmer's original trench.

And, if the strata are the same then some part of the strata the Ingram money was in still exists ... on the exposed bank behind and further inland of the 1980 Ingram find position. So in one sense a sample of those original strata is still available!?

And if that is true then R99's request for 'elevations between Tina Bar and the Flushing Channel (north/south) and the river and NW Lower River Road (east/west)' can be related to the strata at the original elevation and location of the Ingram find....  which I believe is what R99 is trying to determine?

Tom's premise  is very clear right at the opening of his Palmer section, namely:

Fact: Modern day Tena Bar is severely eroded and exposing natural clay layers that run the length of the beach.
Fact: The Palmer Report discovered and interpreted a buried clay layer as man-made from the dredging operation.
Interpretation: Palmer's original report claiming the clay layer was a result of the dredging was inaccurate.


The logic of this is straightforward:  If the clay layer in Tom's photo IS the same clay layer Palmer identified as dredging spoils in 1980, then Tom may be correct and Palmer got it wrong, for two reasons! (1) The 1974 dredging spoils DID NOT go behind Tina Bar to the present site of Tom's 2008 clay layer, and (2) if Tom's photos are near the Ingram find, then that may very well be far enough removed from the 1974 north dredge spoil pile, to remove any clay layer at the Ingram site from being due to dredge spoils?

We are juggling a lot of information and ideas here. Let me just sit and let this settle out...

Shutter I don't know what you mean by: "so much sediment to build up on the beach".

What "so much sediment" are you referring to?

Shutter, do you have the Corps of Engineers data that starts on November 1, 1974 for the Vancouver gage?

I do not. I have a Vicinity/Boundary map, and two photo's with water depths etc. on them....they are big files. I have to send them via email...

Here is a partial for the link to the Corps of Engineers Vancouver water data mentioned above:

Several years ago, the National Weather Service in Portland gave me the link and I printed out all of the pertinent data.  Unfortunately, I do not have the full link any more.

The equivalent data for the period from the hijacking, November 24, 1971, to November 1, 1974, apparently either doesn't exist or never made it online.

I found a survey from 1985. it's too big to post. it has some of caterpillar on it.....

Survey of Columbia river tidelands?
