Mount Mageik is a stratovolcano on the Alaska Peninsula with no confirmed historical eruptions, though its youngest known eruptive products date to the Holocene, roughly between 8750 BCE and 500 BCE. A young crater on the northeast flank of its central summit cone has vigorous superheated fumarolic activity and prominent sulfur deposits. Its cones are composed of andesite, basaltic andesite, and dacite, and its slopes are covered in ash from the 1912 Novarupta eruption and the 1953 eruption of nearby Trident Volcano.
