Massive Ice Wall Blocked Passage for Americans

An icy barrier up to 300 stories 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. These findings show that the first people in the Americas instead arrived via boats along the Pacific coast, researchers said.

 There are two main hypotheses about how people first migrated to North America. The older idea suggested that people made this journey when Beringia, the landmass that once connected Asia with North America, now divided by the Bering Strait, was free of Ice Wall. The new idea suggested that travelers made their way on watercraft along the Pacific coasts of Asia, Beringia, and North America.

Before work regarding the age of the Ice-free corridor suggested, it might have served as the migration route for Clovis people.

Scientists have unearthed a great deal of evidence of a pre-Clovis presence in North America. Nearly 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.
