The Bering Land Bridge National Preserve is one of the most remote Protected areas of the United States, located on the Seward Peninsula. [ 3 ] The National Preserve protects a remnant of the Bering Land Bridge that connected Asia with North America more than 13,000 years ago during the Pleistocene ice age. [ 4 ]
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 ...
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.

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 ...
A Bering Strait crossing is a hypothetical bridge or tunnel that would span the relatively narrow and shallow Bering Strait between the Chukotka Peninsula in Russia and the Seward Peninsula in the U.S. state of Alaska. The crossing would provide a connection linking the Americas and Afro-Eurasia. With the two Diomede Islands between the ...
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]
Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge . This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). [1] Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska.
