Ice Age Ends Smashingly: Did a comet blow up over eastern Canada?
Evidence unearthed at more than two dozen sites across North America suggests that an extraterrestrial object exploded in Earth's atmosphere above Canada about 12,900 years ago, just as the climate was warming at the end of the last ice age. The explosion sparked immense wildfires, devastated North America's ecosystems and prehistoric cultures, and triggered a millennium-long cold spell, scientists say.
IT'S IN THERE. A layer of carbon-rich sediment (arrow) found here at Murray Springs, Ariz., and elsewhere across North America, provides evidence that an extraterrestrial object blew up over Canada 12,900 years ago. The hallmarks include lumps of glasslike carbon (top), carbon spherules (middle, in cross section), and magnetic grains rich in iridium (bottom). West; (middle inset): Cannon Microprobe
At sites stretching from California to the Carolinas and as far north as Alberta and Saskatchewanmany of which were home to prehistoric people of the Clovis cultureresearchers have long noted an enigmatic layer of carbon-rich sediment that was laid down nearly 13 millennia ago. "Clovis artifacts are never found above this black mat," says Allen West, a geophysicist with Geoscience Consulting in Dewey, Ariz. The layer, typically a few millimeters thick, lies between older, underlying strata that are chock-full of mammoth bones and younger, fossilfree sediments immediately above, he notes.
New analyses of samples taken from 26 of those sites reveal several hallmarks of an extraterrestrial object's impact, West and his colleagues reported at the spring meeting of the American Geophysical Union in Acapulco, Mexico.
Samples from the base of the black mat yield most of the clues to its extraterrestrial origin, says Richard B. Firestone, West's coworker and a nuclear physicist at the Lawrence Berkeley (Calif.)

Catastrophism & GGG Ping.
You probably owe me an apology over the ‘scolding’ you gave me about the Carolina Bays (absolutely) not having a celestial origin.
As the freeze/thaw cycle does its work, some rocks rise, and other rocks fall through the soil. The net result is a circle of rocks of relatively similar size.
It's a least energy cost pathway sort of mathematical form.
No doubt one of the effects of the comet was to encourage the continuation of the glacial period for another thousand years, and that would have given us more circles ~ many of them quite large.
I've heard that the Carolinas got pretty cold in the Younger Dyrass. My own frontyard got pretty cold then, and even before that time. You can go back something like 600 million years to the "snowball earth" thing, and find out that recurring glaciation at the latitude where Virginia was located at that time probably created the 100,000,000 trillion glacial rocks located in the disaggregated schist just below the surface of the clay.
I even have a recurring salt spring on this lot!
Why are the circles elliptical and oriented in a direction? At Prudhoe Bay there are similar looking features shaped by prevailing wind.
Why would a comet suddenly “explode” just before impact?
further, why would a comet choose to “explode” and leave a layer of soot across N America like one would expect with a full eruption of Yellowstone?
just asking, LOL
I'm familiar with that action...however, it does not produce iridium or diamonds.
"In samples taken from 15 of the features, Howard and his colleagues found iridium-rich magnetic grains and carbon spherules with tiny diamond fragments similar to those found at Clovis archaeological sites."
When Yellowstone erupts it leaves a six foot deep ash layer as far away as Nebraska. You know, little things like that. (Ahem)
It exploded for the same reason the Tunguska Event did in 1908.
Causing genetic bottleneck?
Go to this map here and 'scoot'over around the Bahamas...I can make out two possibly more suspicious circles in that area that seem to have some alignment to the Carolina Bays.
We are speaking of the ovals and circles on the coastal plaine, right? With the iridium layer being laid down almost simultaneously with the resumption of the freeze-thaw cycle (on a massive scale), all you’ve done is demonstrate that this was a big comet, not that it ploughed holes in the sand.
Why would a comet suddenly explode just before impact?
Picture an enormous celestial mudball with mixed densities hitting the pressurized atmosphere.
Hmmm, comet debris over Eastern Canada...space microbes evolve into...Quebec?
It exploded for the same reason the Tunguska Event did in 1908.
Incidentally, there is no truth to the persistent rumor that the Tunguska Event was caused by Darwin Central! Besides operative Tesla was working on something else at the time!
Some effect, no doubt.
Professor Bryan Sykes says that the Europeans were driven back to the Ice Age Refuges during the Younger Dryas. Professor Stephan Oppenheimer says that some European populations outside the refuges weathered the YD in place...so, there's some disagreement among experts.
Now, some genetists say that the Sa'ami's (Laplanders) left the refuges early at the end of the Ice Age and were isolated from the larger European population for a long time...I wonder if that isolation wasn't during the YD. The Sa'ami are so unique that they are described as having a Sa'ami Motif.
"It is curious, however, that the mitochondrial DNA of the Samis should differ so distinctly from that of other European peoples. The "Sami motif" which has been identified by researchers - a combination of three specific genetic mutations - is shared by more than one third of all tested Samis, but of all the gene tests conducted throughout the world, the same mutation has occurred in only six other samples, one Finnish and five Karelian."
Are you serious about this, or was it a tongue-in-cheek post?
Why would a comet suddenly explode just before impact?”
Damn, that does make sense.
It was J M Adovasio who said that the glacial edge (during the Ice Age) was just north of Meadowcroft that has been dated to at least 16,000 year ago...And, the Topper Site in South Carolina may be as old as 50k. Why would these people hang around in this arctic climate (necessary to create the circles) when they could go to balmy Florida? Maybe it wasn't cold enough there to make the Carolina Bays that way, huh?
The earth atmosphere is very thick, when considering the speed of these objects and the energy they are spilling off.
It's reason Engineers use the term: "Breakup upon reentry"
After all, the “collective memory” of Neanderthals (ugly, hulking brutes, some larger than humans, found in caves, underground and “backwoods” resembles the ogres, dwarfs and giants of mythology.
Also: Dinosaur bones, dinosaur tracks, and T Rex and raptor skulls certainly explain the worldwide similarly and descriptions of dragons in all cultures.
Why are the circles elliptical and oriented in a direction?
Angle of impact.
A 90 degree fall (head on / straight in) makes a perfectly round crater.
A 45 degree angle (glancing blow / side swipe) makes a perfect ellipse.
or a hot fudge sundae /obscure
I read that the Chixlub meteorite entered at about a 35 degree angle coming from the south. I wouldn’t have wanted to be in North America 65 million years ago when it hit.
That seems like one of the biggest problems with this theory. The genetic evidence does not show all of North America being repopulated from a small group of survivors of a catrastrophic event.
Large teeth tend to splay out if the upper jaw is "smaller". This results in the lower teeth achieving a crooked alignment.
Best bet is to restrict breeding to those with larger upper jaws.
Prognathism is no guide to jaw size though ~ just to its position vis a vis the skull.
Here's Winston Churchill's denture:
While a student he went to Lapland to run around, eat the food, live the life for something like 6 months! It's worth reading about his health and that of his father to make you wonder if he/they weren't suffering from being forced to eat a Western diet rather than the high iron reindeer and seal for which they might have been designed.
Linnaeus did the same thing on a grant ~ went to Lapland to study plants and animals.
I think you asked if there were any figures on Sa'ami native intelligence ~ depends on who you count as a Sa'ami. Can't find the diminutive Norwegian Sa'ami in Churchill's woodpile, but I suspect he's there ~ his brand of heart trouble with repeated "attacks" is fairly typical of what you can find among those who inherited one of the genes for Scandinavian porphyria. His father's health problems are certainly typical.
The bottleneck only works numerically. A global striation of life depletion with some vast areas completely blanked out of zoological species above a certain weight range.
Did comet start deadly cold snap?

Rapid heating caused by friction with the atmosphere. Very common for "falling rocks".
Earth In Upheaval
Peculiar elliptical depressions, or “oval craters,” locally called “bays” are thickly scattered over the Carolina coast of the United States and more sparsely over the entire Atlantic coastal plain from southern New Jersey to northeastern Florida. These marshy depressions are numbered in the tens of thousands and, according to the latest estimate, their number may reach half a million. Measurements made on the more prominent ones, seaward from Darlington, show that the larger bays average 2200 feet in length, and in single cases exceed 8000 feet...
(here I go, Google Earth again!)
Freeze Thaw cycles typically produce forms that are hexagonal in shape, not elliptical. I can’t say what these elliptical shapes are, but they do not look like anything formed by freeze thaw.
Try it. Report back.
Ten thousand years of ADDITIONAL weather can do a lot of stuff ~ the circles are known in other places.
Google Permafrost polygonal forms. Lots of research and literature on this topic, including many locations where these forms are artifacts of earlier climatic conditions. Has anyone published a paper suggesting the the Carolina Bays are permafrost artifacts?
Your typical circle or oval as found in nature is obviously a “polygon”.
My backyard and beyond for five miles is pretty much these permafrost hexagons. They are fairly uniform in size, but I would have to guess how big they are. Maybe fifty feet across.
Now, look down the road a couple of centuries to a time when there is no permafrost in the area and hurricanes regularly sweep up the Gulf of Alaska to laywaste Alaskan coastal areas ~ think of what those polygons are going to look like.
When the permafrost melts the land sinks and fills with water. Then the water fills with vegetation and eventually it becomes dry land again. The formation remains so you can see how it came about. Lots of low grade peat around here. We have examples of all stages of permafrost activity including pingos. Fascinating to watch and it changes fast enough to actually see it happen.
And me as well, Renfield, for the caustic lecture you gave me about the demise of North American megafauna. I expressed the (to you) heretical notion that they might have suddenly perished by some means other than over-hunting by Clovis tribes.
While this new theory doesn't give any final answers, it lends credence to my long-held hunch that catastrophism or disease played a much greater role than over-hunting.
Benjamin Franklin was in haplogroup ‘V’ (Sa’ami).
No point in trying to educate muawiyah, he believes what he wants to believe and is not going to be swayed by mere logic, evidence, facts, or anything else for that matter.
I personally think that the Carolina Bays were formed by the Little People, since it is a well known fact that the Irish were here long before Columbus and the Vikings.
“...You probably owe me an apology over the scolding you gave me about the Carolina Bays (absolutely) not having a celestial origin.....”
No, I don’t. Carolina Bays are NOT of celestial orgin; they are, as we discussed before, deflation basins. Many of the bays predate the 12,900 year age mentioned in the article, and some geologic formations have no bays, while other adjacent formations do.
