Bering Land Bridge
It is believed that a small Paleo-Indian population of a few thousand survived the Last Glacial Maximum in Beringia. This group was isolated from its ancestor populations in Asia for at least 5,000 years before expanding to populate the Americas sometime after 16,500 years ago.
Beringia is 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 degrees north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States. The area includes land lying on the North American Plate and Siberian land east of the Chersky Range.
