I'm glad this has finally been put to rest. Per the Ars article: "...that makes for a grand total of 55 radiocarbon results in support of the earlier dates across the three studies."
The evidence of much earlier human habitation in the Americas has been around for decades, yet has always been shoved aside in favor of a hypothesis with all ends tidied up and bound with a neat bow. Humans traveling over ice sheets from eurasia to the americas never made a huge amount of sense when they could skirt it's resource-rich edges - and traveling by water is much faster, and much less calorically intensive than traveling by land. You also have your food readily available.

If this is true, when do you think humans first arrived in North America?
From my reading of the article, the dating of these footprints (~20k years ago) precludes the idea that humans arrived at that time. They must have arrived much earlier, because the northern part of the content was impassable due to glaciers.
...Unless they travelled down the Pacific coast of North America and then moved east.
Columbia river would be my guess.
Explains the Cooper's ferry evidence in Idaho [1].
I hear there is oral tradition from the coastal and Oregon tribes about the glacial "Missoula floods" which took place repeatedly between 10k-20k years ago.

Very cool.
You can still see the ripples from the proglacial lake in Missoula today. [1]

I live in Coeur d'alene, ID...which sits in the Purcell trench. The floods started just north of here at Clark Fork, ID. There is massive evidence of them everywhere you look.
One spot, Chilco mountain, if you look towards the trench it is all flat and if you look the other way it is all mountain/river valleys. This wall separated the floods from the non flooded area. Lots of exposed rimrock here too. Also the reason we have such a good aquifer here (Rathdrum aquifer) which supplys Spokane/Coeur d'alene.
These floods are likely responsible for bringing the 6th largest iron-nickel meteorite ever discovered (on Earth) from the Canada/Montana area to Western Oregon.
I don't have the references, but I know that there have been some discoveries in Latin America and Western South America, that have been very old. Probably not "solid" enough for many scientists, though.

... No-one is suggesting people traveling over ice sheets? In fact, the primary reason for the conventional chronology is that it avoids any ice sheets.
During the last glacial maximum, the sea level was low enough that the entirety of Beringia was above sealevel. It was also not covered by ice, and it was one of the richest places for hunter-gatherers to live north of the tropics. Think less of a land bridge and more of a continent. This allowed access to western and central Alaska, but the way forwards was blocked by the Laurentide ice sheet, both on the continent and extending significantly over the ocean. For someone to cross from Alaska to the southern part of the continent, they would have to sail over 2000km without access to anything but deep ocean and floating ice.

Not exactly. The leading explanation is the "Kelp Highway" theory - the complex coastal geography of SE Alaska and ocean currents could have created a small pockets of ice-free land and given access to rich marine resources. You could effectively island hope down the inland passage until you hit the Columbia river. Having made it to Australia 50kya, we know at least some prehistoric humans had the maritime technology to pull it off.
My take is, it seems likely that at least some of the Beringians made it south of the ice wall during the glacial maxima. If the ice wall was indeed impenetrable 25kya (ie the kelp highway theory is wrong) , the White Sands footprints must have come from people who migrated even earlier.
I think the point still stands that there has been a desperate clinging to a chronology that denies plenty of evidence and essentially all oral tradition of the people in question.
Which oral histories allow us to differentiate between the various hypotheses for the initial peopling of the Americas? I'm not aware of any and it's very difficult to identify direct relationships between modern groups and the earliest groups. Moreover, operationalizing oral histories and tying them to cultural memories of specific historical events is difficult at best, since that's not really how ancient oral histories get preserved.
Ancient oral histories are preserved through constant communication across generational boundaries.
There are too many examples of oral history matching historical events for me to bother being your Google here.
Very little weight has been given to the accuracy of these oral histories until recent times. Meanwhile tribes have been saying “that’s not how it happened” to the Clovis hypothesis the entire time.
