How did the Bering Land Bridge impact history?

Bering Land Bridge National Preserve commemorates this prehistoric peopling of the Americas from Asia some 13,000 or more years ago. It also preserves important future clues in this great detective story regarding human presence in the Americas.

What happened to the land bridge between Alaska and Russia?

The last ice age ended and the land bridge began to disappear beneath the sea, some 13,000 years ago. Global sea levels rose as the vast continental ice sheets melted, liberating billions of gallons of fresh water.

Why was the Bering Land Bridge significant to Native American history?

The land bridge measured about 1,000 miles north-to-south at its maximum extent. Climate change at the end of the Ice Age caused the glaciers to melt, flooding Beringia about 10,000 to 11,000 years ago and closing the land bridge. By 6,000 years ago, coastlines approximated their current boundaries.

How long ago did humans move off of the Bering Land Bridge?

30,000 years ago

Who discovered land bridge theory?

To solve these problems, “whenever geologists and paleontologists were at a loss to explain the obvious transoceanic similarities of life that they deduced from the fossil records, they sharpened their pencils and sketched land bridges between appropriate continents.” The concept was first proposed by Jules Marcou in …
