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.
