Overview

The Aleutian Islands ( ə-LOO-shən or ə-LEW-shən), also called the Aleut Islands, or Aleutic Islands, are a chain of 14 main, larger volcanic islands and 55 smaller ones. Most of the islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located farther to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East. The islands form part of the Aleutian Arc of the Northern Pacific Ocean, and occupy a land area of 6,821 sq mi (17,666 km2) that extends westward roughly 1,200 mi (1,900 km) from the Alaska Peninsula mainland, in the direction of the Kamchatka Peninsula; the archipelago acts as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost and easternmost parts of the United States, by longitude (Amatignak Island and Semisopochnoi Island, respectively). The westernmost U.S. island, in real terms, however, is Attu Island, west of which runs the International Date Line. The islands, with their 57 volcanoes, form the northernmost part of the Pacific Ring of Fire. Physiographically, they are a distinct section of the larger Pacific Border province, which, in turn, is part of the larger Pacific Mountain System physiographic division. The islands are considered to be among the most geographically isolated areas of the Northern Pacific. Battles and skirmishes took place during the Aleutian Islands campaign of World War II. The Japanese landing and occupations of Kiska and Attu, in June 1942, were the only invasions of the United States in North America during WWII; the Philippines, Guam and Wake Atoll, Pacific territories of the United States, were also invaded.
