| | Bering land bridge - Wikipedia, the free encyclopedia |
 | | The Bering land bridge, also known as Beringia, was a land bridge roughly 1,000 miles (1,600 km) north to south at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages. |
 | | The Bering Strait, the Chukchi Sea to the north and the Bering Sea to the south, are all shallow seas (map, right). |
 | | The Bering Land Bridge is significant for several reasons, not least because it enabled human migration to the Americas from Asia about 12,000 years ago (see Models of migration to the New World). |
