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.

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 coastal route. [8] Bering Land Bridge National Monument was established in 1978 by Presidential proclamation under the authority of the Antiquities Act. [9]
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 ...
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.
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]
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
At that time he made a feasibility study of a Bering Strait bridge and estimated the cost to be $1 billion for the 80 km (50 mi) span. [12] In 1994 he updated the cost to more than $4 billion. Like Gilpin, Lin envisioned the project as a symbol of international cooperation and unity, and dubbed the project the Intercontinental Peace Bridge. [13]
