Description: Ward and Matumoto (1967) note that "During August 3-5, 1965, pulverized ash filled the air in the region from the Valley of Ten Thousand Smokes to Brooks Lake. Although several people were within ten miles of Mts. Trident and Martin, the suspected sources, no aerial or ground reconnaissance could establish whether this ash was of volcanic origin or simply windblown (Ward and Ward, 1966.)" Ward also notes that Mt. Martin "fumed steadily" during 1965.

However, Miller and others (1998) don't believe that this is an eruption account, saying "all reports of eruption or ash emission are probably spurious, reflecting only the persistent and conspicuous steam plume. Steam emission is normally vigorous and continuous from the summit vent of Mount Martin with plumes occasionally rising 600 m above the vent and extending downwind for 20 km." Additionally, the 1965 event could simply be 1912 Novarupta ash remobilized by strong winds.
