Massive ice wall may have blocked passage for first Americans [they came by boat]
Live Science ^ | March 21, 2022 | Charles Q. Choi

An icy barrier up to 300 stories high — taller than any building on Earth — may have prevented the first people from entering the New World over the land bridge that once connected Asia with the Americas, a new study has found.

These findings suggest that the first people in the Americas instead arrived via boats along the Pacific coast, researchers said...

Based on stone tools dating back as much as 13,400 years, archaeologists had long suggested that people from the prehistoric culture known as the Clovis were the first to migrate from Asia to the Americas. Prior work regarding the age of the ice-free corridor suggested it might have served as the migration route for Clovis people.

However, scientists have recently unearthed a great deal of evidence of a pre-Clovis presence in North America. For example, in 2021, 60 ancient footprints in New Mexico suggested humans were there about 23,000 years ago, and in 2020, archaeologists discovered stone artifacts in central Mexico that were at least 26,500 years old...

To help solve this mystery, researchers sought to pinpoint when the ice-free corridor opened. They investigated 64 geological samples taken from six locations spanning 745 miles (1,200 kilometers) along the zone where the ice-free corridor was thought to have existed.

I always like the word “may” in the title.

They walked north from the many several hundred thousand year old sites in South America.

I never supposed that humans came here by only one route, and I suspect, as more artifacts are uncovered (who says “global warming” is necessarily a bad thing?) we’ll learn our knowledge about human migration was/is totally lacking in imagination.

Jus’ sayin’

Glacial ice keeps beer cold longer and I don’t know why.

I have to believe that people were here long before 13,000 years ago. Them NOT being here makes little sense when you consider people were just about every other place.

That’s odd, others complain of the allegedly ubiquitous certainties.

There weren't that many people around. And most of them moved to follow food, whether on land or in the sea.

There were people all over the world. Certainly there were huge sea faring communities in India and China. There were certainly lots of folks in South America by then.

I imagine the records of people in North America were wiped out by the glaciers and subsequent deluge.

There is a bunch of stuff we don’t know.

Well duh! I personally figured this out long ago. Sea levels were way down during the “ice age” so most of the coastal settlements they made are now under water. You think they came across the “Bering Land Bridge”? OK, then what? The area between the Brooks Range and the Alaska Range was probably not glaciated but everything else was so you come across from Asia and face walls of ice as you move inland. Keeping to the coast is the only viable means of travel.

If only there had been some man made climate change to melt those massive sheets of ice

This article about an ice wall is correct. One of my ancestors took a picture of it. We’re still not sure how he got a camera. Maybe he got it from a space alien.

Somewhere in the GGG archives should be an article about the narrow land bridge being the hunting grounds of Saber-tooth cats which decimated migrating populations for centuries.
