ALEUTIAN RANGE

segment of the Pacific Coast Ranges of western North America, extending southwestward for about 600 miles (970 km) from the west end of the Alaska Range to the head of Cook Inlet of the Gulf of Alaska, U.S. The Aleutian Islands represent a southwest extension of the mountain peaks, which stretch the length of the Alaska Peninsula and include many volcanoes, notably Katmai (6,716 feet ) and Veniaminof. The range, named for the Aleuts who inhabited the island region, embraces Lake Clark National Park and Preserve, the Katmai National Park and Preserve (including the Valley of Ten Thousand Smokes), and the Aniakchak National Monument and Preserve.
