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 ...
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.

With the two Diomede Islands between the peninsulas, the Bering Strait could be spanned by a bridge or tunnel. There have been several proposals for a Bering Strait crossing made by various individuals and media outlets. The names used for them include "The Intercontinental Peace Bridge" and "Eurasia–America Transport Link". [1]
With the rise of sea level after the Last Glacial Maximum (LGM), the Beringian land bridge was again submerged. Estimates of the final re-submergence of the Beringian land bridge based purely on present bathymetry of the Bering Strait and eustatic sea level curve place the event around 11,000 years BP (Figure 1). Ongoing research reconstructing ...
This is commonly referred to as the "Bering land bridge" and is accepted by most, though not all scientists, to be the first point of entry of humans into the Americas. There is a small portion of the Kula Plate in the Bering Sea. The Kula Plate is an ancient tectonic plate that used to subduct under Alaska. [9]
The islands were once mountain tops in the central portion of the land mass known as the Bering land bridge. [7] The first European to reach the Bering Strait was the Russian explorer Semyon Dezhnev in 1648. He reported two islands whose natives had bone lip ornaments, but it is not certain that these were the Diomedes.
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 was via a ...
Until 11,000 BCE, the territory of the park was connected by a land bridge – known as "Beringia" – to North America.On the eastern side, in Alaska, is the Bering Land Bridge National Preserve, operated by the US National Park Service.
