|Start:||December 1778 ||Observed|
|Eruption Type:||Not an eruption.|
Captain James Cook saw Redoubt during the summer of 1778, "emitting a white smoke but no fire which made some think it was no more than a white thick cloud such as we have frequently seen on the Coast, for the most part appearing on the sides of hills and often extends along a whole range and at different times falls or rises, expands or contracts itself and has a resemblance to Clouds of white smoke. But this besides being too small for one of those clouds, remained as it were fixed in the same spot for the whole time the Mountain was clear which was above 48 hours" (Beaglehole, 1967).
Kisslinger (1983), translating Doroshin (1870) notes that George Vancouver was also in the area in 1778 (Lamb, 1984) and does not make any mention of Redoubt steaming.
Although Simkin and Siebert (1994) called this event a questionable volcanic eruption, the Smithsonian Volcanoes of the World online database now calls this event a discredited eruption, stating that there was no ash emission during this event. Wood and Kienle (1990) also do not call this event an eruption.
