Aleutian Islands
A volcanic island chain arcing some 1,900 km from the Alaska Peninsula toward Kamchatka, separating the Bering Sea from the Pacific Ocean.
Alaska is both the westernmost and easternmost U.S. state. The Aleutian Islands cross the 180th meridian, so Amatignak Island lies near 179°W while Semisopochnoi Island reaches about 179°E.
