This picture was taken on a rare clear day from

Chukotka, Alaska by Dr. Ken Tankersley in 1995.

The scene is the Bering sea and the mountains of
Eastern Siberia on the horizon. Archaeological sites

in Siberia are far older than any of North America's

earliest  Paleo sites. Solid uncontroversial dates
in America are still only around 12,000 to 14,000 old.

But most North American Paleo archaeologists 

generally agree that early migrations into the New

World must have occurred sometime between

25,000 and 50,000 years ago.
