Description: From Neal and others (1995): "Kupreanof is a deeply eroded stratovolcano with no known historical eruptions. Holocene debris avalanche deposits have been recognized, however, and there is a vigorous fumarolic area marked by sulfur deposits at an elevation of 1,524 m (5,000 ft). Steaming from Kupreanof has been noted in the literature as 'eruption reports' in the past (Smithsonian Institution, 1987).

The Smithsonian Institution (1987) reports that "MarkAir pilot Jerry Chisum observed ash and steam emission from a solfatara field on the SSW flank [of Kupreanof]."
