McGimsey and Wallace (1999) write that "On Wednesday, June 3, 1997, a U.S. Coast Guard helicopter crew reported greenish discoloration on snow and steaming from several vents on a 7,000-ft-high (~2,100 m) peak north and east of Mt. Katmai. A minor anomaly was noted on satellite imagery and the source of the activity was suspected to be either Snowy Mountain or Kukak Volcano, both of which have active fumaroles (Wood and Kienle, 1990). During the early 1980s, fumarolic activity was more vigorous at Kukak than at Snowy (C. Nye, oral communication). Both volcanoes are extensively ice covered [see fig. 9 in original text]. The fumarolic activity and lack of significant erosional dissection of the flanks suggests youthful activity; however, no historic eruptions have been reported."
