Description: The Anchorage Daily News reported on October 20, 1938, that U.S. Coast and Geodetic Survey crews of the ships Pioneer and Surveyor had reported "Mount Tulik on Umnak Island" active during the summer of 1938. The deeply glaciated nature of Mount Tulik (Coats, 1950; Miller and others, 1998) indicates that it has not been active within historic time. Eruptions attributed to Tulik are almost certainly eruptions at Okmok instead. Coats (1950) reports this eruption as occurring in October; this date probably references the date of the newspaper article and not the date of the eruption, which seems to have occurred sometime during the summer months. Powers (1958) reports a lava flow associated with this eruption, as well.
