It is a fairly well accepted theory that many thoudands of years ago, the
ancestors of the Eskimos, as well as Native Americans, travelled from Eurasia to
North America on an "ice bridge" which formed in the Bearing Strait. This
bridge temporarily connected the two continents.
As I understand, this occurred during the last Ice Age. During this ice
age, much of the earth's water was locked up in a giant ice sheet that covered
each of the poles. As more water that would regularly have been in the oceans
was locked into the ice, the sea level went down. The distance between the
continents was drastically reduced.
When the ice did begin to melt, the sea level again rose, increasing the
distance between the continents. Today, however, that distance is so great that
the ocean cannot fully freeze, and you are forced to fly to Asia.
Unfortunately, you will have to cancel your road-trip. You are about
10,000 years late.
