caption_attribution_description: English: Unimak Island, Alaska, United States - September 1992 Seen in this southwest-looking, low-oblique photograph is Unimak Island, Alaska, the largest island in the Aleutian chain. The major volcano on the island (snow-capped peak at the center of the photograph), Shishaldin, rises approximately 9400 feet (2860 meters) and has been active during the last 175 years, with several eruptions occurring recently. The volcano is known locally as "Smoking Moses." At the southwestern end of the island is the snow-capped Pogromni Volcano. The blue lake situated in a large volcanic caldera, which can be seen midway between the Pogromni and Shishaldin volcanoes, is the result of a now extinct volcano that collapsed.
