Beringia sea levels (blues) and land elevations (browns) measured in metres from 21,000 years ago to present. Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula.

During much of the glaciation, sea level was low enough to permit land animals, including humans, to occupy Beringia (the Bering Land Bridge) and move between North America and Siberia. As the glaciers retreated, glacial lakes were breached in great glacial lake outburst floods such as the Kankakee Torrent , which reshaped the landscape south ...
During the glacial epoch this bridge was a migration route for people, animals, and plants whenever ocean levels fell enough to expose the land bridge. [5] Archeologists disagree [ 6 ] whether it was across this Bering Land Bridge , also called Beringia , that humans first migrated from Asia to populate the Americas, [ 5 ] [ 7 ] or whether it ...
Map of Beringia showing the exposed seafloor and glaciation at 40,000 years ago and 16,000 years ago. The green arrow indicates the "interior migration" model along an ice-free corridor separating the major continental ice sheets, the red arrow indicates the " coastal migration " model, both leading to a "rapid colonization" of the Americas ...
The coastal migration hypothesis is one of two leading hypothesis about the settlement of the Americas at the time of the Last Glacial Maximum.It proposes one or more migration routes involving watercraft, via the Kurile island chain, along the coast of Beringia and the archipelagos off the Alaskan-British Columbian coast, continuing down the coast to Central and South America.
Beringia, the land that connected Eurasia and North America during the last glacial period; Bølling–Allerød interstadial, a warm period toward the end of the last glacial period; Cat gap, a gap in the North American cat fossil record 25 to 18.5 million years ago; Eemian, the last interglacial period
The glacial retreat has an interesting side effect, an increase in the frequency of earthquakes in the region. The Wrangell and Saint Elias mountain ranges that spawn the Bering Glacier were created by the collision of the Pacific and North American tectonic plates [the Pacific Plate is sliding underneath (being subducted by) the North American ...
The Bering Strait has been the subject of the scientific theory that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels – a result of glaciers locking up vast amounts of water – exposed a wide stretch of the sea floor, [1] both at the present strait and in the shallow sea north and ...
