context_page_description: Adak Island is an island near the western extent of the Andreanof Islands group of the Aleutian Islands in Alaska. Alaska's southernmost town, Adak, is located on the island. The island has a land area of 274.59 square miles, measuring 33.9 miles on length and 22 miles on width, making it the 25th largest island in the United States.
  Due to harsh winds, frequent cloud cover, and cold temperatures, vegetation is mostly tundra at lower elevations. The highest point is Mt. Moffett, near the northwest end of the island, at an elevation of 3,924 feet. It is snow covered the greater part of the year. Adak, Alaska, is its largest and principal city.
  The word Adak is from the Aleut word adaq, which means "father".
