Re: CPTBIL's mention of Aztec pictographs in SE Arizona

Isn't that making an assumption that they didn't realize their geographic location? Based on (admittedly much more modern) Amerindians surprising knowledge of the geography of America, for example look at Sacajawea's guiding of Lewis and Clark, whom could have predicted her knowledge of such a vast area? There is evidence that Pimas of southern Arizona were aware of Susquehannocks in PA, and many other instances come to mind. So I respectfully disagree on this point.

Yes, but only on that single practice. The Nenana made and used bifaced stone tools quite unlike the microblade technology found in Asia. Then too the Nenana culture also did not apparently spread southward into America, as if something were blocking their path. Like a gigantic continental glacier, for instance...
The oldest Nenana sites date to 11,000 years ago too - when the oldest known Clovis sites date back 13,500 years, so Nenana cannot be the ancestors of Clovis.

Ah yes - qualified OPINIONS we could list ad nauseum - however the geologists have fairly proven that no such ice-free corridor existed in the time frame it has to be there for the Bering Strait land bridge migration theory to work, in fact from 21,000 years back it was closed, covered with glaciers clear across the continent. (Geology) Of course it is possible (though unlikely) those proto-Americans simply hiked across the tops of a thousand miles of glacier, so left no clues to their passing that way - without any available fuel, game etc it would have been quite a journey. So the other choices are the coastal route (using the sea) or to have crossed earlier than 21,000 years ago - also possible.

Is it so "natural" to expect a culture to suddenly change their practices, when the terrain of America they first entered was virtually identical with that of Asia? I would much sooner use light weight wooden poles than heavy bones, however we are back to a similar question, if this habit evolved here, why didn't it spread back into Asia? When it comes to the habit of building a shelter, ancient peoples seem to have been quite resistant to change. For that matter, modern folks are also somewhat resistant to change when it comes to housing... (We can buy lightweight and inexpensive tents that we could live in rather than build huge masonry and wooden structures, yet we don't. )

<Oroblanco wrote>One then has to wonder why these Clovis people with the new, improved tools, cooking techniques etc didn't spread back across the land bridge? What could have prevented them?"
There could be many reasons but the strongest, IMHO, would be the length of time they had been gone from Siberia.
We are talking generations here, and they didn't even realize they had left their original homeland. The land changed little until they reached the interior of Alaska, which was infinitely better than anything they had seen during their migration.

The oldest people found in Alaska belonged to the Nenana Culture. They built their fires on the open ground with no preparation. Does that sound like your Siberian mammoth hunters?

I believe just as many qualified opinions can be found for the ice free corridor as against the theory. It would take weeks to list them all. While there is no physical evidence, it's a popular theory.....with legs, so to speak

There is ample evidence that the mammoth hunters of Siberia did construct tents. Once they arrived on this continent, and the mammoth became scarce, they naturally changed their methods of construction. If you could build a tent using slender wooden poles, would you continue to use mammoth bones
