The Bering Strait is the passage that separates Alaska in North America from Asia.12

Located between the Bering Sea and the Arctic Ocean, the strait is approximately 53 miles (85 kilometers) wide at its narrowest point. The international boundary between the United States and Russia passes through this region. During the Ice Age, lower sea levels transformed the area into a land bridge, which facilitated the migration of plants, animals, and humans between the two continents.13
