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.

Figure 2. Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia (long chronology, single source model). The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. [1]
Studies between 2004 and 2009 suggest the possibility that the earliest human migrations to the Americas may have been made by boat from Beringia and travel down the Pacific coast, contemporary with and possibly predating land migrations over the Beringia land bridge, [2] which during the glacial period joined what today are Siberia and Alaska ...

[6] [7] The former is the determinant factor for the number of gene lineages and founding haplotypes present in today's Indigenous populations. [7] Human settlement of the Americas occurred in stages from the Bering Sea coastline, with an initial 20,000-year layover on Beringia for the founding population.

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]
Dated to around 11,500 BP, [1] Upward Sun River is the site of the oldest human remains discovered on the American side of Beringia. [2] The site was first discovered in 2006. The layer with the human remains at Upward Sun River is most similar to the level 6 layer from Ushki Lake, Kamchatka .
