These are not necessarily the ancestors of the people who were here when the Spanish and other Europeans arrived. I don’t think there’s anything political about it.

It’s very interesting and it would be interesting to see the artifacts.

Wouldn’t it be hilarious if there was already a population in the America’s that was then displaced by “Native” Americans that camp over the land bridge?

My thought was that they were going to refute the idea that people came to North America through the land bridge. If native rights fanatics can say they were “always here” it makes their claim as victims even stronger.

Me, too -- and handle and examine them under magnification.

The most significant observation was that the flakes appear to have been detached by a blow from a soft hammer, like bone or wood.

Soft hammer (aka"billet") knapping is a sophisticated, finely controllable knapping technique. Early cultures relied on hard (stone) hammers exclusively -- until some genius discovered that a soft hammer enabled the controllable removal of long, sharp, thin flakes by causing the (prepared) striking platform to fail in tension (not compression or shock, as with a hard hammer).

Even before I visited the site, I'd love to have samples of that "green limestone" to experiment on -- with a range of hammer materials and knapping techniques. Then, I'd have some known results to compare with the found "artifacts" -- so I could judge them myself.

My big question is, "How did those prehistoric folks manage to see well enough for tool-knapping -- back in the dark depths of that cave?"

P.S. Congratulations, Sam Gamgee, you just exposed the "shiny heinie" of your ignorance for all of FR to see...
