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) is the highest peak. Part of the volcanic belt that rings the Pacific Ocean, the Aleutian Range has been active in recent years, notably at Katmai (see Katmai National Park and Preserve).

The Aleutian Range is a major mountain range of southwest Alaska, extending from Chakachamna Lake (80 miles/130 km southwest of Anchorage) to Unimak Island, at the tip of the Alaska Peninsula. It includes all of the mountains of the Peninsula. It is especially notable for its large number of active volcanoes. The mainland part of the range is about 600 miles (1000 km) long; the Aleutian Islands are (geologically) a partially submerged western extension of the range that stretches for another 1,600 km (1000 mi). However the official designation "Aleutian Range" includes only the mainland peaks and the peaks on Unimak Island.

The range is almost entirely roadless wilderness, and Katmai National Park and Preserve, a large national park within the range, must be reached by boat or plane.

The core Aleutian Range can be divided into three mountain groups. Listed from southwest to northeast, they are:

• Mountains of the Alaska Peninsula and Unimak Island
• Chigmit Mountains
• Neacola Mountains

See Aleutian Islands for the continuation of the range to the west of Unimak Island. Also, just to the north of the Aleutian Range, and sometimes considered part of it, are the Tordrillo Mountains.
