"...I don't have a cable-modem, so Google Earth is out for me. FWIW, I took this as a strawman. Where there's a will, there's a way?..."
Google Earth specifically states that users need high-bandwidth connections, which I don't have at home. We wanted to load google earth on our work computers, but were forbidden to do so. Those were my only options. I'd love to have it, but can't at the moment.
"...Rather than sending me to some group of amateurs... Tacky. Just tacky. Not to diminish the pros, but you would agree that "amateurs" have made significant contributions in various disciplines over the years? I have come to a "trust by verify" mode from the scientific community. Inherent problems with that approach should be obvious for a layman...."
Peer-reviewed journals exist in order to weed out wild speculation. There is nothing "tacky" about insisting upon the use of credible sources.
"...Just one other point re the elevations(~5,000') some of these bays/oriented lakes are found and associated marine sediments. Tectonic forces have raised areas that were previously near or even under water? Is there any other explanation for this anomoly?..."
I don't know which bays/oriented lakes you refer to here, but tectonism affects every place in some way or another. A geologist sent me an abstract on Friday concerning some work he's been doing in our area, which suggested (among other things) that this area (Southern Maryland) had been uplifted ~40 meters in the last 37,000 years (mostly, he thinks, due to forebulge during the Wisconsinian glacial maximum). 5000 feet, however, is quite a bit of uplift to have occurred during the relatively short interval of the Quaternary period.

Please see if you can review this paper:
Daniels, R. B. and E. E. Gamble. Relations Between Stratigraphy, Geomorphology and Soils in Coastal Plain Areas of Southeastern U.S.A. Geoderma, 21 (1978) pp. 41-65.
This will help acquaint you with coastal plain stratigraphy. Geoderma is an arcane and outrageously expensive journal; you'll probably have to go to the library of the agronomy department at your nearest land-grant university to find it.
The "oriented" lakes in South Africa at ~5000'. I also didn't mean to imply(although it may have looked like it) there were marine sediments associated with these particular formations, but more generally about marine sediments found at great elevations in other parts of the world. Most, but not all of these sediments are really old; the Alps, Himalayas, etc.

I ran across an article in my searches reaching a similar conclusion.

I doubt I'll go quite that far, but I did run across this from HERE:

There is nothing to indicate distances and the time periods aren't much help either. If you could maybe flesh it in a little???
