University of Copenhagen researchers Eske Willerslev, Mikkel Pedersen, and their colleagues found that this harsh route only became viable for human migration 12,600 years ago—when the first plants and animals showed up in the region. Meanwhile, archaeologists have ample evidence that people were living in the Americas long before then.
“We know conclusively that human groups were in the interior before that date—perhaps as early as 15,000 calibrated radiocarbon years before present—so it is highly unlikely that they came south through the corridor,” said Michael O’Brien, an anthropologist and current academic vice president of Texas A&M University–San Antonio, who wasn’t involved in the study. “A more likely scenario is that they came south along the Pacific coast.”
For the study, Pedersen and colleagues drilled sediment cores from beneath the frozen surface of two lakes in western Canada: Charlie Lake and Spring Lake. These were among the last areas to lose their ice cover when the two huge ice sheets that blanketed the region (the Laurentide and Cordilleran ice sheets) split during the end of the last glacial maximum, around 15,000 years ago. The retreating ice opened up a path some 1500 kilometers long into the interior of North America.

The results of the study suggest the route was only usable between 12,600 and 10,000 years ago. This narrow window is too late to match with the once-prevailing “Clovis First” hypothesis...
Recently, several before-Clovis sites have been discovered in the Americas. Fossilized feces more than 14,000 years old have been found in Oregon’s Paisley Caves. Stone tools alongside mastodon bones in Florida were recently found to be 14,550 years old. And much further away from northwestern Canada, in southern Chile, humans inhabited Monte Verde at least 14,000 years ago (and possibly even earlier).

Stone stools?
Well played, sir.
Yes, and now she has no hope because Trump will become President.
When they looked back after they crossed, they could see Russia from there.
Ive always held to that date range since Indian legend quotes a god coming down on a pillar of fire at meteor crater in AZ. Unless they were way more geologically intuitive than given credit for, it was seen by people.
So the “Native Americans” stole the land from somebody else.

They’re not interested in written history; they wish to invent fairy tales of an imaginary time.

I have read it- several times and use it for a reference. The chapters about agriculture (trees and fire) are fascinating.
Just skirt the coastline/icepack in kayaks.
Fish, hunt seals, camp overnight, repeat. Dress warmly.

I like the speed boat myself.
Um, how does one carbon date a STONE tool? Unless there was a wood handle attached, the material would be older by a factor of 10, 100 or 1000.
It was just 20-30 years ago that the date of 12k years ago was SETTLED SCIENCE amongst the EXPERTS. Does that suggest anything to those who have the senses and intelligence that God Gave us?
For non-Government-dependent scientists, the concept of SETTLED SCIENCE went out with Aristotle and Ptolemy! One of the greatest achievements of Western Civilization is organized scientific inquiry and one of it’s most basic tenants is that a theory is always subject to dispute and disruption as facts can render it void.
Example: Benjamin Franklin was only one of many to note that the ocean borders of Africa and South America were impossibly aligned. In the 1910s&20s, German scientist Alfred Wegener added fossil & geological evidence to make a claim that the Continents Drift but the geophysicists rejected his claim because they could not see any mechanism for such movements. It took new facts derived from oceanography and vulcanism to establish that mechanism in the 1950s.
As for human settlement in the Americas, I give a raspberry every time I see a ‘documentary’ on “Who Discovered America”, because it is both obvious and immaterial. Obvious in that the permanent discovery was the one by Christopher Columbus and immaterial in that there were so many before his expedition as to be meaningless.
My semi-educated guess is a strong and foolish sailor on a strong raft who got caught in a storm off Europe and survived the Westerlies to make it to the Americas. He probably lived well but died very lonely . Rinse and repeat many, many times until actual societies made it who could sustain themselves. Could be by the Bearing Straight or by sea-ice routes from Europe during the Ice Ages. DNA appears to show that the Amerind populations were the last great migration and came from Asia.
Unless there is definitive proof that the Siberians had no boat or canoe or rafting technology, this does not seem like a hugely important issue.
I have also read in other sources that rising sea levels after the last Ice Age ended most likely washed away all traces of pre-12,600 ya North American coastal communities, if any actually existed.
Yes, well, I think Earth is a penal colony.
The stone tools were found in a peat bog, and the peat, which is rich in organic material, was dated to 14,500 years old.
