An incredible record of human life at that time

Therefore, people undoubtedly inhabited North and South America long, long before the last ice age.

>5 Rood: Do you mean much earlier than when this record was made?

>6 stellarexplorer: Obviously. The people responsible for the art works didn't just fly in from Asia to that specific region, just for the purpose ... They must have inhabited South America for centuries ... or longer ... before settling down in
that one area long enough to cover 8 miles of stone with drawings and paintings.

Which also suggests people must have lived in North America long before the last Ice Age, too.

The Last Glacial Period (LGP) occurred from the end of the Eemian to the end of the Younger Dryas, encompassing the period c. 115,000 – c. 11,700 years ago.
Thus it's perfectly possible early humans reached North and South America towards the beginning of the last glacial period. After all, thousands of years passed before the ice sheet reached its maximum extent.

>9 Rood: Perfectly possible is not the standard I am personally drawn to. One piece of evidence that would raise my level of suspicion is the presence of humans in northeast Asia in the early part of the period you suggest. I am not aware of such a presence until tens of thousands of years later. Of course I am very interested in early signs of human habitation in the Americas and what conclusions we might draw.

Yes, we'll probably never know for sure, but the notion people entered North and South American only during and after the period ... when the last continental glacier was melting ... just doesn't seem to hold water.

I just hope you're right that the most recent Ice Age turns out to be the last one.

Ha! I crack myself up. :)

Yes. The last ice age ... until the next, anyway.

I grew up in a rural part of North Dakota, where fascinating evidence of the last glacier was all around: levery type of moraine, kames, kettles, outwash channels, eskers, erratics from the Laurentian Uplands of Canada ... some bigger than a car, stratified drift ... all fascinating stuff

The only question: Will global warming speed up the process?

Now that it has become public knowledge, I hope it will be protected from looters and vandals.
