Mount Iliamna

Iliamna Volcano, or Mount Iliamna, is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot volcano lies approximately 134 miles southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.

The volcano's glaciers have extensively altered its profile, cutting, deep and creating steep cliffs and cirques. A ridge extends 5 kilometres south from the main body of the mountain, with North Twin and South Twin peaks along its length. There is no summit crater, only a zone of fumaroles just south of the summit at the top of large collapse zone at the head of Red Glacier, which exposes a cross section of the mountain.
