The Bering Strait is not measured in length, as it is a narrow sea passage that splits the Asian and North American continents. The Bering Strait connects the Bering Sea to the south and the Chuckchi Sea to the north. The Bering Strait is approximately 51 miles wide.
The Bering Strait's depth ranges between 100 and 165 feet. It is named after Vitus Bering, a Russian mariner. The official boundary between Russia and Alaska lies in the middle of the Bering Strait at the islands of Big and Little Diomede. According to archaeologists, Russia and Alaska were connected by a land bridge during the last Ice Age, which wore away over time from strong winds and ocean currents.
