Beringia is the prehistoric region spanning eastern Siberia and northwestern North America, bounded roughly by the Lena River in Russia to the west and the Mackenzie River in Canada to the east, and including parts of Siberia, Alaska, and Yukon. During glacial periods it included the Bering land bridge, a land connection up to 1,000 kilometers wide and roughly as large as British Columbia and Alberta combined, formed when lower sea levels exposed the floor of the Bering Strait. The region is central to the history of human settlement of the Americas: a small population of at most a few thousand people is thought to have reached Beringia from eastern Siberia during the Last Glacial Maximum, sometime before about 23,000 to 21,000 years ago, before expanding southward into the rest of the Americas.

It is believed that 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 Last Glacial Maximum (26,000 to 19,000 years ago).

Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St.
Introduction (2)
Beringia is a prehistoric geographical region, defined 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 underlying mechanism was first thought to be plate tectonics, but by 1930 changes in the ice mass balance which led to global sea-level fluctuations were viewed as the cause of the Bering land bridge.

At various times, it formed a land bridge referred to as the Bering land bridge or the Bering Strait land bridge that was up to 1,000 km (620 mi) wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling about 1.6 million km2 (620,000 sq mi), allowing biological dispersal to occur between Asia and North America.
