a land bridge joined present-day Alaska and Russia in a kind of pre-cold war geologic detente. The bridge "rose" from the ocean as vast amounts of ocean water became tied up in the enormous glaciers of the last ice age. That exposed the broad continental shelves now covered by the Bering Strait and created the land bridge.
The bridge last arose around 70,000 years ago. For years, scientists thought it disappeared beneath the waves about 14,500 years ago, toward the end of the last ice age. Unfortunately, that was about 2,500 years before the first accepted date for human settlement in the new world.
