The Pleistocene/Holocene Impact Site

[jusdennis]

I hope folks can excuse the awkward first steps of a newbie. But
if someone here is already kicking this around. Or are talking about the Clovis Culture and possible reasons for their decline, or demise in another thread I'll post what I've got there.

I think I've got a pretty good handle on where the comet that's been postulated by some exploded. Would folks like to talk about it here, or is there another thread that's already talking about it?

Have moved this into chat as it is not a question about Archaeology Live!

Anybody have any thoughts?

Well, In a round about way does oertain to archaeology because it also involves the Clovis culture, and what may have happened to them. I'm refering to the following research by R.B. Frirestone et al.:

Evidence for an extraterrestrial impact 12,900 years ago that contributed to the megafaunal extinctions and the Younger Dryas cooling.
And in another paper by C. Vance Haynes Jr.
Departments of Anthropology and Geosciences, PO Box 210030, University of Arizona, Tucson, AZ 85721
Entitled:

Younger Dryas ‘‘black mats’’ and the Rancholabrean termination in North America

The problem I am faceing is that, while radiographic and micrographic analysis of the rocks at the epicenter have not been done too postively confirm it. There is a, clearly visible from space, high energy blast structure that covers most of eastern North America. And if visual confirmation were enough that would be it. But it's size, and apparent age being just what R.B. Firestone et al. predicted brings us to a conundrum of highest magnitude.
It ties up many loose ends in archaeology and Meteorology.
The visual evidence is sound and compelling. But it's mere existance if confirmed as a blast structure of extra terestrial origin overturns almost every theory we have about landform creation. Specifically those that were postulated before the world saw S.L. 9. untill then the idea that an extraterestrial impact event could have continent wide geological significance would have been considered absurd to say the least. So don't ask a geologist to help you with this. He will point you to the vary theories the thing overturns for reference.

Are there any Archeologists working on this?
