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]
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 Beringia's long history some animals migrated Easterly (mastodons, gomphotheres, mammoths, various members of the deer family, bison, sheep and muskoxen) others Westerly (equines, camels), and yet others reveal many episodes of dispersal (such as lemmings and voles).
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 ...

Old Bering Sea is an archaeological culture associated with a distinctive, elaborate circle and dot aesthetic style and is centered on the Bering Strait region; no site is more than 1 km from the ocean.
Beringia is in the Bering tundra ecoregion. The region experiences a Subarctic climate, without dry season (Köppen climate classification Subarctic climate (Dfc)).This climate is characterized by mild summers (only 1–3 months above 10 °C (50.0 °F)) and cold, snowy winters (coldest month below −3 °C (26.6 °F)).
Floating Coast: An Environmental History of the Bering Strait is a 2019 book by Brown University historian Bathsheba Demuth, published by W. W. Norton & Company. [1] The book examines environmental and social change in the Beringia region surrounding the Bering Strait from the mid-nineteenth to the late-twentieth centuries, focusing on the pursuits of American and Russian interests and their ...
The Seward Peninsula is a remnant of the Bering land bridge, a roughly thousand-mile-wide swath of land connecting Siberia with mainland Alaska during the Pleistocene Ice Age. This land bridge aided in the migration of humans, as well as plant and animal species, from Asia to North America.
