McGimsey and others (2004) write that Willie Hall, a pilot with Kodiak Air Service, "reported seeing about 15 vents [fumaroles] on Kukak Volcano, which he described as deep holes in the summit ice field, with most on the upper west flank and about 3 on the east side. In his 23 years of flying over the area he had never seen fumaroles on Kukak before. Wood and Kienle (1990) describe 'a vigorous fumarole field on Kukak's northern peak [that] keeps that area free of ice and reveals the volcanic character of Kukak.' A U.S. Coast Guard helicopter crew reported in June of 1997 seeing steam rising from several vents from a high peak northeast of Mt. Katmai, presumably on Kukak (McGimsey and Wallace, 1999)."
