Beringia

1. The Bering land bridge, a geographical phenomenon roughly 1,000 miles (1,600 km) wide (north to south) at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages; the land bridge previously occupying what is now the Bering Strait.
   • 2006, Michael R. Bever, "Too Little, Too Late? The Radiocarbon Chronology of Alaska and the Peopling of the New World", American Antiquity:

     Note that, while not in Alaska, one site from the adjacent Yukon Territory has been included as well; it, too, would have been within easter Beringia during the last glaciation.

2. All the land between the Lena river in Russia and the Mackenzie river in Canada
