Alaska, United States
Mount Mageik is a stratovolcano on the Alaska Peninsula. It has no confirmed historical eruptions (one in 1946 is now deemed questionable), but its youngest eruptive products are apparently Holocene in age. A young crater lies on the northeast flank of the central summit cone, and is the site of vigorous superheated fumarolic activity with prominent sulfur deposits.
The volcano is mantled in ash from the 1912 eruption of Novarupta and from the 1953 eruption of nearby Mount Trident.
