Pleistocene North America
and Beringia



Beringia was the "land bridge" that widely connected Asia with North America during glacial intervals of the Pleistocene, as so much water was retained in continental glaciers that sea level was considerably lower.

Glacial advance reached a peak 20,000 years ago.

The Clovis culture of mammoth hunters entered North America approx. 13,000 years ago, when glacial meltback opened an ice-free corridor east of the Rockies.
