Description: Steam plumes were observed at Mt. Hague on July 13, 1991. This activity probably does not constitute a volcanic eruption.

From Reeder (1994): "At about 1100 on July 13, 1991, Richard Mack of King Cove observed from his fishing boat, Janice, in the region of Volcano Bay a white plume that was being emitted from within the summit crater of Mt. Hague. The plume reached a height of about 300 m above the peak of Mt. Hague and had drifted to the SW just beyond the crater rim. The day was unusually cloudless. The white plume could be seen all day. By 2100, the plume was slightly smaller and was drifting WSW beyond the summit crater, but the plume was barely rising above the summit of the volcano. The plume was visible from Pavlof Bay until about 2145 when darkness occurred."
