Formerly called the Catherine Archipelago, the Aleutian Islands
comprise some 150 mostly volcanic islands extending twelve thousand
miles west of the Alaskan Peninsula. The major island groups, from
east to west, are the Fox Islands (including Unimak and Unalaska),
Islands of the Four Mountains, Andreanof Islands (including Adak),
and Near Islands (including Attu). Good awnswer :)
