In considered this possibility some years ago (large ice chunks and tsunami).
What if the tsunami banged into the scarp face and the biggest heaviest chucks stopped there as the water and bergs washed back, leaving them in decreasing size as it retreated.
"I'm convinced that the earth is frequently...bombarded by...metorites."
The book "Comet" by Carl Sagan and Ann Druyan, 1997 has a lot of interesting information on the causes of boloid movement through the inner solar system, especially from the Oort Cloud.
Ah yes, it's a pleasure to e-talk with an intelligent person as it's a real bore with some of the dufusses on FR. My nephew told me about FR, and he's "lexinom". I got BIT once by a pit bulldog, came THAT CLOSE to shooting the owner. I'm scotch-welsh-irish-english-german by ancestry but my mother does have red hair. The celts were originally based in austria, known as the keltoi by the greeks, and famed for their copper working skills. Some opine that there was no inter-breeding between homo-sap and Ns, too great a genetic distance apart. Still an open question. It may be that the celts were a homo-sap/N hybrid group and we see the results today as Arnold Swartzenegger!
I thought about that, too. (By the way, if you stand in the surf on the beach, in the waves, watch as the retreating water washes around your feet. It sculpts the beach sand into a shape that looks like a carolina bay.)
In order for stranded icebergs to have been the cause of bay formation, there would have to have been many icebergs off the coast of Georgia and South Carolina. Those areas had warm currents (the Gulf Stream) even then, so icebergs would have been highly improbable. Also, during the glacial maximum, sea level was as much as 330 feet lower than it is today. A tsunami would have had to be large enough to raise the coastal water level by around 600 feet in order to reach the upper coastal plain...and it would have been along a 1000-mile stretch of coastline...I don't think there's been a tsunami like that at any time during the tertiary period.
Well, I take that back. The meteorite that hit off the coast of Virginia at the end of the Eocene might have been able to cause one that large. However, the climate was warmer then....not glacial....and sea level was much higher than it is now.
No Problem. Actually, the electical disturbances wasn't caused by the meteor traveling through the atmosphere, it was caused when the meteor exploded near the surface. The explosion was tremendous, I mean I saw it from nearly 2000 miles away, and thought I heard a crackling sound soon after. It was bright red, and aparently fairly high in the atmosphere when it happened. The one in NM was a greenish color. I asked an astronomer at our local observatory and he told me the colors represented the types of metals in the meteor. Red being iron, I think, and green being either copper or magnesium.
Very interesting reference, Ren. Could you could look it up and post the author and publication of the work (in Charlerston County, S.C) showing that "large Carolina bays overlay infilled river channels (incisions that were refilled during a marine transgression)"?
It would be great to have this information for my on-going Carolina bay study.
Am I correct that this work (paper, presentation, data?) is evidence confounding to the recent and simultaneous origin of bays as some propose. How so? If I may, what is the relevance of infilled river channels and marine transgressions?
I am not geologist but do not understand.
Perhaps reading the paper can help. Thanks to you, and FGS, for posting.
An EMP??? It certainly seems plausible. I've really got to do some looking around for more information on this stuff!
You're welcome. It is an interesting subject. The creation of the bays tends to bring out peripheral subjects also. For example, would you think an exploding comet or other intruder might produce an electrical disturbance, similar to an EMP, in the......force??? Never occurred to me before, but then I haven't really studied ET encounters that much.
I just saw a short article in a local news sheet, saying that using some old Neanderthal bones, scientists are going to try to sequence the entire N genome. Do you think I should post the article as a thread?
On the subject of lightning in strange places. In the course of studying vulcanism, plinian eruptions, and severe pyroclastic flow, I was surprised to discover that heavy lightning was a major association.
Regarding sources of tsunamis and large ice as high as 600 feet, how high do scientists think the tsunami caused by a great chunk of mountainside sliding into the sea in the Canary Islands might have been?
In a separate vein, I have come to a moderately strong belief that there was an important boloid event associated with the Younger Dryas. At that time sea ice extended far down into the Atlantic. My intuitive hunch has been that the boloid whould have been in the upper north Atlantic. Any evidence for or against? As I said this is a strong hunch. Years ago I read something about tectite strew fields in Georgia and/or the Carolinas. I think the age they mentioned was around 12kya. Any info on this?
Ah yes, do. Then pose the question : is Arnold Swartenegger a neanderthal throwback from austria(where the celts originated).
FGS, this link and associated material should be right up your alley now: http://abob.libs.uga.edu/bobk/caseof.html
Before posting the article I saw, I did an FR search of Neanderthal Genome and found the info has already been posted several times in much more detail. Look there for what I was going to post and lots more.
BP = Before Present, a bit more erudite-sounding than "YA"
There doesn't seem to be a lot of agreement on the size of a tsunami generated from there. I've seen anywhere from 100' to 300' as estimates. Bottom line, it would be a doozy regardless.

Can't add anything to your comments but if you're able to dig up something else, it could be very interesting.
OMG, MORE reading!
I'll take a look ;^)

Huh. Looks like that $47 I spent at the Enormous Chain Bookstore yesterday wasn't the last trip until fall, after all. :') Maybe I'll check the email, see if I've got more coupons. I love the CD selection, there's a young kid who likes odd old stuff, like ISB (broke up circa 1975).
