C-14 is not that great for very, very ancient data. If I recall, it’s most suited to the 20,000 to 1,000 BP (Before Present, present being 1957, the year the procedure was invented).

True.

I suggested C-14 because I think the bays may have been formed less (and perhaps much less) than 20,000 years BP.

Thanks for this link as well!

I think you may be referring to Clube and Napier? Just in case...

Good point; it will be interesting to see what the rest of the articles show. I could cheat and just look it up on google or wiki, but this is good science writing.

[ADemocratNoMore]

If you point Google Earth to 34 degrees N by 86.5 degrees W at an altitude of around 600 miles, you can see a semicircular structure running along the boarders of Alabama and Mississippi. Anybody have any ideas?. I can't help wondering if it may be evidence of an ancient impact site.

Great book. I really think this is a very valid hypothesis for the formation of the Caroline Bays, the death of the megafauna, and the end of the Clovis culture. Although this book proposes a highly involved cause for all these effects, they go into considerable well written detail about the scientific effort to verify their hypothesis. Highly recommment it.

Incidentally, is the few paragraphs posted the whole article, or was a link to rest of it not posted?

The modern concensus among soil scientists (of which I am one,and I have spent many years working in Carolina Bays) and geomorphologists, is that the Bays are deflation basins, and are not related to bolide impact.

[wolfcreek]

It seems they’re all lined up in the same direction. (including maximum rim heights)

This would seem to point towards impacts.

[Renfield]

Ahem..they are all pointed DOWNHILL (toward the ocean), which indicates that there is a hydrologic component.

OSL dating gives a variety of late Pleistocene-to-early Holocene ages for the bays, which argues that they were not formed all at the same time. Further, the distribution of the bays, with respect to their sizes, is not random, as we would expect if the cause were bolide impact. The largest bays tend to be nearer the toes of scarps, with average size decreasing with seaward distance from the scarps.

[Renfield]

p.s. OSL dating studies also indicate that the rims postdate the bays.

Remember, the climate during the Younger Dryas was dryer and windier than it is now, and there was much more aeolian movement of soil particles than is the case today. The most likely explanation for the rims is that airborne soil particles dropped out of suspension as the wind velocity decreased on the lee side of the bays.

[wolfcreek]

I see.

[wolfcreek]

I guessing a predominant NW breeze?

[Renfield]

Wind-scatter rosettes indicate a predominantly NW wind during the P-H boundary.

Today, the dominant winds are NW from December to April, and SW from May to November. March tends to be the windiest month, and I have vivid memories of working outdoors during sand storms in March in the Low Country of South Carolina.
