Shishaldin Volcano seen from a fixed wing aircraft in March 1997. Shishaldin is one of the most active volcanoes of the Aleutian arc with periods of low level eruption that can last many months. Even during non-eruptive periods, a visible plume of gas and steam is often seen rising from its gaping summit crater. In the distance in this view is Westdahl Volcano on the southwest end of Unimak Island.
