Westdahl Volcano

Westdahl Volcano is a broad stratovolcano on Unimak Island near the western end of the Alaska Peninsula, part of the tectonically active Aleutian Range. It has two principal summits: Westdahl Peak at 5,118 feet and the higher Faris Peak at 5,426 feet. Rising in one of Alaska’s most geologically active regions, Westdahl has a recorded eruptive history from the late 18th century through the early 1990s, with several eruptions once misattributed to nearby Pogromni Volcano. Because Pogromni is now regarded as an older, eroded peak that likely has not erupted since Pleistocene time, Westdahl is recognized as the active volcanic source and an important feature in Alaska volcanology.
