The strait that separates Alaska from Russia is known as the Bering Strait. This narrow waterway connects the Arctic Ocean to the Bering Sea and separates the Russian Chukotka Peninsula from Alaska's Seward Peninsula. The strait is about 85 kilometers (53 miles) wide at its narrowest point and historically served as a land bridge (Bering Land Bridge) during the last Ice Age. Today, it is important for navigation, wildlife migration, and geopolitical considerations.
