But only one of the causes you cite, contain all the others as derivatives- comet/meteorite impact and implies that all the other causes and their potential observed evidences could be the result of an impact event. None of the other causes contain a)nano-diamond formation or b)blast fragments in the bones of North American megafauna. Native American activist Vine Deloria in his “Red Earth, White Lies” pretty much lays to rest the “hunting to extinction” notion.

It is essential that humanity shift from a concentration on global warming as an all nations inclusive strategy to comet/meteor impact avoidance. The implications of a comet impact, as shown by archaeology, are orders of magnitude more grave than any hypothesized weather event. This initiative would act as a new space exploration “science driver” and do for world economies what JFK’s man on the moon effort did in the 60′s.

i can not understand why it is never mentioned in discussions of dryas climate changes, the position of the earth. 13000 yrs ago the earth was tilted toward the sun in winter as usual. what is unusual is that, at that time, the earth was 3 million miles farther away from the sun. using the inverse square rule, this would cause the earth to receive 7% less sunlight which would result in a significant reduction in surface temperatures in the northern hemisphere. significant enough that, when included with the other factors, it could be the deciding factor that forced the climate change that made the northern hemisphere an inhospitable home for paleo american life.

read your posting, no matter that you still don’t touch on what you initially observed when you state that you observed sth,especially the not overlapping of the flows is a completely clear argument, however i disagree the mountain shows no signs of alluvial distribution, it actually shows a surprising nr of rivlets, however, (although i have ofcourse not had opportunity myself to examine that) the ejecti strata similar features are completely apparent despite of it. the story became clear. (yes these don’t look like 45Ma ignimbrites and there should be a giant caldera to show for it, etc.(flow tubes) however why do you say we don’t have impact craters identified on earth? there are really 100s or 1000s . maybe i misunderstand sth. btw although the magnetical centre of the binairy earth moon system is within the earths crust it is not anymore in the centre of it. as a result there are quite a few meteorites that pass between earth and moon that might have otherwise hit us. (a sixth more gets attracted by the system though the moon, yet the nr of misses could be actually even greater since part of the statistically earthbound meteorites will also miss and the theoretically moonattracted ones will statistically hit the moon , or in the case as it is, may miss the moon as a result of the magnetic centre being a part of the binairy and not the moon only, but would tehn still miss the earth easily)

i fear will not retrive it, but could you elborate on what kind of features you distinguished on the landsat and later images? my interpretation is you noticed blast erosion patterns? perhaps duststreaks? i would very much like to hear more of it and thank you for even this slight contribution heartfelt. as to the technicality’s firestone’s remarks here are completely plausible, such layers are very thin, i remember i disagreed with the initial findings however, mostly because i thought they underestimated (biasedly) the impact of human hunting behaviour on extinction. also i know about at least one meteoric impact around 12kya (on saremaa island estonia) wich has also been preserved in local myths. since they (comp. eg shoemacher levy), tend to come in bunches there is nothing implausible about a seperate impact in north america. very interesting. maybe you want to check the saremaa impact for wich well established impact brecci including microdiamonds are found. naturally they should be of likely composition in the case of a related event.

[...] did a fine job explaining why this is so in person at AGU. But on Anthropology.net — linked here and excerpted below — Rick Firestone gives a fine written critique of the flawed methodology [...]

If it is ok to take a firm stand on one side of the debate, or the other, I’ll cast my lot with Dr. Firestone, and friends.

I was trained to do battle damage assessment in the military. And it has been an interest ever since. A long time ago, when the first LandSat images became available to the general public, I noticed some explosive blast effects in the southwest US, and central Mexico that couldn’t be believably explained by standard theory in the light of the new hi-res satellite images. At the time I knew nothing of any work on the Younger Dryas cooling. And it was long before anyone had proposed fragmented comet impacts. But it was a wonderful conundrum. I knew I was looking at the ground effects of an unimaginably violent event that flew in the face everything I had ever learned. And I knew of no natural energy release to account for them. For that matter I knew of no kind of natural energy release at all that could do what I was seeing.

The ground effects, and blast effected materials, I had noticed all seemed to point to something that happened around the end of the last Ice age. And, when I learned of work on the Younger Dryas Boundary layer, and the nano-diamonds R.B. firestone et al, and others had found there, I realized they confirmed some of what I had found. It confirmed, if nothing else, that an event of the level of destruction I was looking at did indeed happen. And recently enough too.

From what I can see R.B. Firestone et al are spot on.

There is no end to the theories related to to the so called Younger Dryas impact event. Some are good, and some not so good. And I’ve no doubt, you have heard them all by now. But here’s a fresh viewpoint that looks at the actual ground effects of such an event from a fluid mechanics / blast analysis point of view: http://sites.google.com/site/dragonstormproject/

Actually, there are several techniques for diverting an Earth impactor. The non-nuclear charge ones require early detection; if you can’t accept that, then mitigating the effects of impact require early warning as well, such as food storage and or evacuation from soon to be impacted areas.

In any case , early warning is the key, and we have better technologies to do this with, if we choose to employ them.

Some of the First Peoples remembered what appear to be comet fragment impacts:

http://forum.palanth.com/index.php/topic,1093.0.html

Not all of these can be classed as fossil myths, and note that a number of them were recorded before we had any idea of an “Ice Age”.

Undoubtedly a complex set of factors led to the extinctions. Any one: Hunting, new hunting technologies, climate change, impact, sudden climate change and hyper disease, does not rule out another occurring.
