Mount Sergief description and information

From Smithsonian Institution, online database, accessed December 8, 2003: "Sergief is a small stratovolcano on SW Atka Island whose age is poorly known. The SW part of the island is older and less topographically rugged than the NE part of the island. Sergief was tentatively listed as a young volcano in the Post-Miocene Volcanoes of the World catalog of the International Association of Volcanology and Chemistry of the Earth's Interior (1973), but the age of its latest eruption is not precisely known."
