THE BERING STRAIT This 53-mile-wide body of water separating the Eurasian and North American continents was originally a land bridge between the two: a 2,000-mile-wide stretch of arctic tundra, flush with wild game and humans. At the end of the Ice Age, the world's glaciers melted, raising the ocean level by some 300 feet. The low-lying land was submerged, creating the strait as it is today. |
