Timeframe puts such an event during the near-extent of the last ice age. I grew up 35 miles east of the Mississippi River. For any one else that has driven up and down the Mississippi and Missouri River valleys, the further north and west you go, the broader the valleys gets. What caused the bluffs to rise 500 feet from the valley floors nine miles apart. Sound like a lot of melt water during a very short period to cause that kind of upheaval. In the Upper River Valleys, the bluffs are a ridge parallel to the rivers, not eroded or cut out from erosion like further south.
only 2 documentaries eh? Soon to come on Discovery channel...”Comet week, see the Earth destroyed in Hi Def!”
Here we go. More talk about the comet.
ping!....
All species are subject to cycles of sustained growth and sudden calamity.
The classical symptoms of a species in crisis include:
1. Increased aggression
2. Sexual dysfunction
3. And disease.
Here is an earlier article about the impact event mentioned in this article. Did it exterminate the Clovis folks? Don't know yet...interesting ideas though.

I've often wondered if the Barringer Impact 50,000 years ago wiped out these even earlier folks mentioned in the link below.
The oldest human skeleleton ever found in the Americas was found on the Channel Islands.
'Arlington Springs Woman', 13,000 Years Old Human Skeleton, California Island
And also about the same time. We don't know what happened to these folks:
"The oldest human remains found in the Americas were recently "discovered" in the storeroom of Mexico's National Museum of Anthropology. Found in central Mexico in 1959, the five skulls were radiocarbon dated by a team of researchers from the United Kingdom and Mexico and found to be 13,000 years old. They pre-date the Clovis culture by a couple thousand years, adding to the growing evidence against the Clovis-first model for the first peopling of the Americas."
"Of additional significance is the shape of the skulls, which are described as long and narrow, very unlike those of modern Native Americans.
Any scientist worth his salt can come up with six or seven theoretical explanations for anything.

Maybe some of these folks?
In life one makes bad decisions from time to time. I was within 20 miles of Clovis New Mexico and consciously made a decision not to go.
The road beckoned and apparently had a stronger pull.
Maybe next time
Si-te-cah? They were most likely Vikings who sailed thru the Bering straits during a warming period (GLOBAL WARMING TO BLAME!)..........Much too young to be connected to the others......
.....into the Laurentide Ice Sheet north of the Great Lakes.......
That would be the Hudson Bay Basin in my view. If you observe the map closely, the object came in low from the northeast, making a trough before it dug in.
Nah. Most likely related to Spirit Cave Man who lived in Nevada 9,400 years ago.

A nuke won’t do it. A thousand nukes have been detonated with no noticeable effect on the climate.
You've hit upon something that piques my curiosity whenever I think about; that is, around here river bottoms and creek bottoms are much wider than present flows. Erosion? Possible, but I suspect at some point in the past there may have also been enormous water flows from some source. Just a curiosity...
JMO, but Barringer Crater seems a little smallish to have created much havoc. Locally, it would have been quite a show though.
I STILL believe paleo types' best bet for finding artifacts or other evidence of really old "new" world civilizations will be on the continental shelves. Or even around the edges of dried up lakes, like Bonneville, or even near ancient river and creek beds. Like Topper for example.
Yeah...the next Ice Age will provide an archaeological bonanza when the water recedes again.
I wouldn't wait too much longer bert. You ain't exactly a spring chicken ya know, ahem.
On a similar note, whan I was a youngster, I had two uncles in the concrete business. The loads of gravel that came in invariably had arrowheads in 'em; some in perfect condition. Nobody thought much about 'em at the time since finding arrowheads was not all that uncommon around here. The gravel likely came from a source nearby, probably one of the river bends. Entirely possible they were of recent vintage, anyway...
Holy Cow! That thing almost hit the highway!
