Exploding asteroid theory strengthened by new evidence located in Ohio, Indiana
Space & Earth science / Earth Sciences

Geological evidence found in Ohio and Indiana in recent weeks is strengthening the case to attribute what happened 12,900 years ago in North America -- when the end of the last Ice Age unexpectedly turned into a phase of extinction for animals and humans -- to a cataclysmic comet or asteroid explosion over top of Canada.
A comet/asteroid theory advanced by Arizona-based geophysicist Allen West in the past two years says that an object from space exploded just above the earth's surface at that time over modern-day Canada, sparking a massive shock wave and heat-generating event that set large parts of the northern hemisphere ablaze, setting the stage for the extinctions.
Now University of Cincinnati Assistant Professor of Anthropology Ken Tankersley, working in conjunction with West and Indiana Geological Society Research Scientist Nelson R. Schaffer, has verified evidence from sites in Ohio and Indiana -- including, locally, Hamilton and Clermont counties in Ohio and Brown County in Indiana -- that offers the strongest support yet for the exploding comet/asteroid theory.
Samples of diamonds, gold and silver that have been found in the region have been conclusively sourced through X-ray diffractometry in the lab of UC Professor of Geology Warren Huff back to the diamond fields region of Canada.
The only plausible scenario available now for explaining their presence this far south is the kind of cataclysmic explosive event described by West's theory. "We believe this is the strongest evidence yet indicating a comet impact in that time period," says Tankersley.
Ironically, Tankersley had gone into the field with West believing he might be able to disprove West's theory.
Tankersley was familiar through years of work in this area with the diamonds, gold and silver deposits, which at one point could be found in such abundance in this region that the Hopewell Indians who lived here about 2,000 years ago engaged in trade in these items.
Prevailing thought said that these deposits, which are found at a soil depth consistent with the time frame of the comet/asteroid event, had been brought south from the Great Lakes region by glaciers.
"My smoking gun to disprove (West) was going to be the gold, silver and diamonds," Tankersley says. "But what I didn't know at that point was a conclusion he had reached that he had not yet made public -- that the likely point of impact for the comet wasn't just anywhere over Canada, but located over Canada's diamond-bearing fields. Instead of becoming the basis for rejecting his hypothesis, these items became the very best evidence to support it."
Additional sourcing work is being done at the sites looking for iridium, micro-meteorites and nano-diamonds that bear the markers of the diamond-field region, which also should have been blasted by the impact into this region.
Much of the work is being done in Sheriden Cave in north-central Ohio's Wyandot County, a rich repository of material dating back to the Ice Age.
Tankersley first came into contact with West and Schaffer when they were invited guests for interdisciplinary colloquia presented by UC's Department of Geology this spring.
West presented on his theory that a large comet or asteroid, believed to be more than a mile in diameter, exploded just above the earth at a time when the last Ice Age appeared to be drawing to a close.
The timing attached to this theory of about 12,900 years ago is consistent with the known disappearances in North America of the wooly mammoth population and the first distinct human society to inhabit the continent, known as the Clovis civilization. At that time, climatic history suggests the Ice Age should have been drawing to a close, but a rapid change known as the Younger Dryas event, instead ushered in another 1,300 years of glacial conditions. A cataclysmic explosion consistent with West's theory would have the potential to create the kind of atmospheric turmoil necessary to produce such conditions.
"The kind of evidence we are finding does suggest that climate change at the end of the last Ice Age was the result of a catastrophic event," Tankersley says.
Currently, Tankersley can be seen in a new documentary airing on the National Geographic channel. The film "Ancient Asteroids" is part of that network's "Naked Science" series.
The new discoveries made working with West and Schaffer will be incorporated into two more specials that Tankersley is currently involved with -- one for the PBS series "Nova" and a second for the History Channel that will be filming Tankersley and his UC students in the field this summer. Another documentary, this one being produced by the Discovery Channel and the British public television network Channel 4, will also be following Tankersley and his students later this summer.
As more data continues to be compiled, Tankersley, West and Schaffer will be publishing about this newest twist in the search to explain the history of our planet and its climate.
Climate change is a favorite topic for Tankersley. "The ultimate importance of this kind of work is showing that we can't control everything," he says. "Our planet has been hit by asteroids many times throughout its history, and when that happens, it does produce climate change."

Comet Theory Collides With Clovis Research, May Explain Disappearance of Ancient People
When Obama! is POTus and the DNC is in full possession of both houses, we’ll get laws passed that protect us all from esplodin space things!!
General/Chat/Science/Astronomy is ideal for this topic, and your others.
This is new, news.
So this interglacial being the longest of the last five could be due to a premature exploding-asteroid thaw?
So is Paris Hilton dropping her pants. Everything is news if you think about it that way. On FR we have categories.
The "mother load" seems to have been a deposit of some sort on top of the Bradford Woods ridge (in Morgan county), another large deposit on top of the second highest elevation in the region called Mt. Nebo, and the highest called Weed Patch Hill (all in Brown county).
Early miners simply tossed shovel loads of soil off the side of the hill and the rain would wash off the lighter materials and the heavier stuff would eventually slide down the hill where it could be readily extracted through very simple mechanical means.
They didn't need to use cyanide in this process.
The fact that so much of the lode was on the tops of hills led early researchers to assume the glaciers, which stopped near here repeatedly through many ice ages, left the diamonds and gold as they retreated.
At the same time Mt. Nebo and Weed Patch Hill were NOT inundated by ice. The valleys in the formations in Brown County were cut by running water, not ice. There turns out to be little glacial till even half way up these shale hills.
Further South in Jackson and Clark counties, where there were glacial hills called "knobs", there were little or no deposits of gold and diamond. Closest thing to that were the fools gold (iron pyrate) and native copper deposits that could be found in the early pioneer period.
Folks who'd observed the anamolous distribution of the loot wondered if maybe it hadn't just been dropped out of the sky!
Here, you'd have low trajectory diamond laden ejecta raining down on hills, valleys and everywhere in between.
As the great glaciers melted at the end of the Younger Dyras, they created a massive river that worked its way back and forth across Indiana for several thousand years destroying all in its path. The only places that weren't washed away were the tops of the shale hills, and that's right where the gold, silver, diamonds and other neat stuff was found.
Here is my posting history:
You've posted a total of 11,104 threads and 59,606 replies.
I've always posted this way, year after year, made dollar-a-day donations and not fought with anyone. Why have you chosen to harrass me now? Do you want me to leave FR?
BTW, as DeSoto made his advance from Mobile Bay North to Terre Haute in 1541 the Indians he encountered correctly pointed toward this particular deposit of diamonds and gold.
They didn't lie to him.
In the end he sent out an expedition from his base in Terre Haute to travel overland toward what today you might call Cincinatti. They missed the gold and diamonds by 5 miles or so yet they did find the small native copper deposit.
Blam, I think she thinks you’re a “newbie”! (bwahahahahaha!)
Yeah, but not nuclear missiles as that kind of defensive weapon is aggressive.
I believe that puts me several thousand replies behind Blam.
By now I suspect he and I know the difference between "news" that really is "news", and the sort of stuff you might dig up in National Inquirer about Paris Hilton (gag, what a skank) and force us to scroll on by.
In the future if you wish to reference one of the Hollywood braintrust folks in an effort to chasten us please use Lindsay Lohan. She has some Class A picture spreads ~ in the meantime, back to further recent discoveries of why the rocks are piled up the way they are in Indiana.
This is hardly one of those Leftwingtard EMO blogs where that's the name of the game.
You may very well not appreciate the "news" value here, but it is "news" in all the right circles.
Imagine that, after you doing the same. The only difference here is, I can pull my own replies.
Do you want me to leave FR?
F*** NO! You stay here! Many Freepers enjoy your posts. Keep'm coming!
Fascinating. Thanks for posting this.
You may not appreciate this, but the few remaining scientists here will. Or you trying to drive the last of us away too?
This post deals with finally answering a question that has been bugging archaeologists and prehistorians, not to mention glacial geologists and a lot of other specialists, for decades.
Thanks for the post. I enjoy and appreciate current news regarding science, specifically news regarding astronomy.
Science/Astronomy would be ideal for this topic, but we don't have this category.
Or is General/Chat/Science/Astronomy a new category? Shouldn't other categories be renamed, also? Like:
Religion/Astrology
Smokey Backroom/Dark Matter ?

Canadian diamonds in Indiana? Who knew? I guess I’ll be digging up my back yard this weekend looking to strike it rich. Just my luck and Canada will claim ownership like Spain does with sunken ships.
...and now you know the *real* reason the Soviet Union, oops, I mean Russia, has tried to claim the Arctic Ocean... ;’)
This is very big news and explains extremely important changes regarding development of climate and life in North America 12000 years ago. It also explains the total destruction of the civilization here at that time.
Or is this another anti-science pre-purge warning?
Hmmmmm. Doesn't that make this news, business/economy, foreign affairs, government?
(just stirring the pot)...
Thanks guys, as always for the interesting posts. This one comes with the added fun of a Moderator scuffle! =)
Clearly science is about as newsworthy as Paris Hilton, although possibly less interesting. *headdesk*

;’) Historically speaking, that falls under “bearding the lion in his den”. Or, in the context of Russia, “don’t poke the bear”. :’D
Science has to share one with Paris Hilton?
Gentlemen, (and Lady) we need a Science Forum.
It's been my observation that General/Chat is where real news goes to die. People who thirst for substantive news simply don't go there because of all the Paris Hilton crap.
May I suggest that we consider adding a Science/Technoloy forum?
FR is a political discussion board, so there are multiple subboards which are specialized; all non-political stuff goes in Chat or Blogs. :’) I wouldn’t mind Science forum, but I’d really love to see a ghetto for the Gossip topics first.
Ummmmmmm...
Make that Science/Technology...
:’) It’s not that fun for me.
*shrug* It’s like slapstick. Much more fun to watch than experience...
Quite literally the gold miners in Morgan and Brown counties Indiana moved on to California BEFORE gold was discovered at Sutter's Mill (formerly the centerpoint of the Russian colony in California).
They were there to take advantage of that discovery INSTANTLY. I've suspected for a long time that they'd already found placer deposits (similar to what they'd worked in Indiana and Ohio) in Diamond County and simply kept things quiet.
Of Note: Not all the gold miners left Indiana. Many of them stayed in the area and took advantage of the white oak forests to create a serious basket industry.
I love that part where the flower squirts someone right in the eye...
Gold was first discovered in southern California, but it was a small placer deposit and was quickly panned out. It simply didn't last long enough to cause a gold rush.
No doubt the Spanish looked wherever they could in Southern CA but they never really got a grasp on the North.
