Woolly mammoth movements tied to earliest Alaska hunting camps

Is this source wrong that buffalo was a primary part of the Navajo Diet? That would seem to be a natural in the four-corners region. https://www.indiancountryextension.org/the-navajo-people-and...
The massive herds of Bison you're thinking of were primarily a feature of the great plains. Bison existed across much of the rest of the continent, but in much less overwhelming numbers towards the periphery outside the plains. The modern Navajo nation is right on the edge of that historical range. The Sioux (the Lakota among them) are one of the larger ethnolinguistic groups on the plains, along with others like the Blackfoot I mentioned. Here's a rough and highly imperfect map of the "territories":

Also, this is a matter of some disagreement between the ivory tower and many of the Diné themselves, but it's a bit ambiguous to use the term Navajo prior to the Long Walk in the 1870s, when the Bison range had already retreated onto the plains. Navajo prior to that are usually identified much more closely with other Apachean groups. The technical term here is "ethnogenesis".
We don't know the historical range of Na-Dene or Lakota, or other modern nations; we know only where they were centuries after the aforementioned pandemics wiped out a large majority of all populations across two continents.
The current Pueblo habit of adobe dwellings is suited to their now-confined range. One may reasonably doubt those living in wetter climates used them.
We don't actually know how they hunted the mammoths.
What’s next? We can only imagine: eating tiny insect purée from a chewing-machine in the comfort of our shared condo-room, with the A/C at full power
My hypothesis takes that further and shows that it was the biggest cultural change in human history creating the concept of “capital” and is now counter productive to the long term success of humanity
Consensus seems to be that it’s combinatory between loss of habitats from warming and over consumption
Hunting to extinction is a holdover from "Clovis First" doctrine.
Stop with the assumptions
That’s taken into account for in acceleration, however megafauna extinction events start 50kya and are confidently correlated with human population increases.
This paper discusses YD in the all cause:
We have no reliable data about human population levels in North America, so nothing to correlate to extinctions.
The North American megafauna, 30+ genera strong, were wiped out by the end-Pleistocene comet strike that caused continent-wide wildfires 12,800 years ago, as recorded in Antarctic and Greenland ice cores. This comet strike coincided with the beginning of the Younger Dryas cold spell, and is suspected of causing it. North America at the time boasted giant sloths, mastodons, mammoths, dire wolves, camels, horses, saber-tooth cats, and beavers, bison and bears much larger than what is left. Their fossils mostly appear right up to the continent-wide black mat of platinum-enriched soot, and not above it.
So those remaining of people who had been making Clovis spear points were obliged to shift to hunting the smaller game that remained, and made the smaller Folsom and other projectile point styles after. The continent-wide uniformity of Clovis points before the strike may have been a consequence of their status as trade goods, where deviation would reduce their value. After, the trade networks may have been disrupted, or maybe smaller points were easier to make, so were less valuable to trade. Most questions will probably never be answered.
There is a good survey article on the status of the end-Pleistocene comet strike by Martin Sweatman. Follow references from there to Antarctic ice cores. (Boslough and Holliday have a great deal to be ashamed of.)
There are all sorts of things that can influence consumption patterns. Change in climate could result in fewer sources of food as drought or inclement stunted certain crops which cascaded into fewer food sources for upstream predators where at the apex we had our fore-bearers who may had decimated populations till there were not enough to sustain the species.
But the link is broken for me, and so this is a comment on just the headline.
The article itself states that the camps were set to capitalize on the mammoth movements - 'It looks like these early people were establishing hunting camps in areas that were frequented by mammoths.'
