Aleutian Range

Aleutian Range, volcanic mountain chain, c.1,600 mi (2,600 km) long, SW Alaska, extending W from Anchorage along the Alaska Peninsula, and continuing, partly submerged as the Aleutian Islands, to Attu island. Mt. Redoubt (10,200 ft/3,109 m), an active volcano, is the highest peak. Part of the volcanic belt that rings the Pacific Ocean, the Aleutian Range contains many active volcanoes. The sites of some of the most notable eruptions are in Aniakchak National Monument and Preserve, Katmai National Park and Preserve, and Lake Clark National Park and Preserve.
