Amazing what one can find, if one digs long enough. Sort of like web archaeology.

This paper is yet another paper by Firestone, West, et al regarding the evidence. this appears to be the PNAS paper and it very detailed. It also shows that Topper DID have a black mat although a better description might be, a black line, very thin layer of extraterrestial sediments.

PDF well worth looking at if this topic interests you.

Thanks, Monk.

Great find.

Well I probably should clarify one important point. In the previous post, I said Topper had a black mat but that is not actually the case in the sense it was a layer of charred biomass. It is more correct to say that Topper has a layer of extraterrestial sediments at the same stratigraphic layer as the other sites, immediately on top of the Clovis-era strata.

Well, Monk. Now I know you actually read the article!

Thanks for posting the PNAS reference. Like you, I am wary of comets falling out of the sky to explain events such as the YD. However, I will eventually yield to the science, whatever that may be. What we need here is the Wayback Machine to figure out what happened.

From the News Page a few days back.

This brings up lots of interesting possibilities.

“No ice bridge across the Bering Sea.”

“And just within the last year, new research has provided strong evidence that a large meteorite struck the ice sheet covering North American and melted much of the ice shortly before the formation of the Kankakee Sand Islands.”

Lake Michigan would not have had to be much higher than now to create dunes in Porter, Ind.
It is not that far away from the current shoreline.
But if the water was that high, the lake would certainly have had a drainage into the Illinois River, maybe even the Wabash River, and thus to the Mississippi.
If the early settlers followed the rivers, they would have had some big ones to follow from a starting point in the South or Southeast in North America.

It would settle my point in the past about the Asian type micro-lithic tools seeming to be absent from NA.

More interesting stuff...............

hoka hey,

How come it was a racist comet?

Maybe it was a case of survival of the fittest?

Has Collins reported any thing about an ET "Black Mat" found at the Texas Gault site? OR---was it all concentrated up north?

See figure 9 in the addendum to this article:

http://tsun.sscc.ru/hiwg/Activity/Firestone+25_2007.pdf

for a map of the "black mat" sites.

Another goofy non-starter hypothesis.

If there were merry bands of boaters cruising up and down the Pacific Coast they might have been shielded by the Rockies.

There wouldn't be anyone in the blast zone because Canada was under a few miles of ice at that time.

First hurdle: IF a comet or meteor exploded over Canada, why did it wipe out all the Solutreans/Clovis People, but not the Paleo Indians?
Must've been a racist meteor...
A whole new concept!

It definitely didn't wipe out any Solutreans, they were gone 7000 years before this happened.
