According to Lambert's Washington: A State of Contrast, the ocean level was several hundred feet lower than it is now. That means that there could potentially be a land mass hundreds of feet below the surface of the ocean connecting Siberia and Alaska. Scientists also discovered huts, fire pits, and ancient skeletons on the ocean floor in the Bering Strait. That means that Native Americans were traveling across the land bridge in the Bering Strait thousands of years ago.
