I don't know anything about bays in South Africa. can you send me a reference?
Glad to. In my searches for additional "bay" evidence I ran across a group of Google Earthers who apparently spend much of their time searching for bay type features around the world. They have located many such features, most of which have what appear to be identical characteristics to the Carolina bays. Many, like I said, nowhere near any oceans past or present, and some at elevations above 1500'.
If you'll start HERE you can go to the various sites where bay type features have been found so far. The Australian and South African sites are the most interesting, but there are others as well. Click on the individual posters "placemarker" to go to the particular site they have found(You'll need to load the Google Earth program if you don't already have it).
Now, due to my lack of communication skills I have apparently not made one point in particular very well. ~120,000 years ago sea levels were at their highest recorded level during the past 500,000 years. It was ~30m(~125') above current sea level. So it would seem to me that any bay type feature above ~125' would not be a good candidate for ocean hydrologic activity since sea levels have never been higher than that. I may be missing something, but it wouldn't be the first time.
Re the absence of shocked quartz associated with the bays; FWIW, the Tunguska impactor apparenlty left little trace of itself behind either. Another note re Tunguska: One descripton of the first people on the site found NO crater, but a few "sinkholes" in the vicinity. Sinkholes???
There's still another point I'm forgetting(which is par for the course I'm afraid), but maybe it will come back to me.
