Description: From Reeder (1990): "At 1500LT ( = GMT - 10 hours) 28 August 1987, Scott Kerr and Pete Galaktionoff, residents of Dutch Harbor, observed from Chuginadak Island as they were climbing Mount Cleveland steam emissions from the summit of Carlisle volcano that rose for several hundred meters. Such steam emissions were common during the latter part of August.

"Pilot Harold Wilson of Peninsula Airways Inc., who has flown the region numerous times between September 1983 and July of 1987 has never noticed any steam emissions from Carlisle volcano. Harold feels that if any steam emissions occurred from this volcano during his flights between September 1983 and July 1987, such emissions must have been very minor and certainly nothing like the steam emissions observed by Scott and Pete.

"At 1359LT 16 November, Lieutenant Dave Holman (Captain) and Lieutenant Jay Brown (co-pilot) observed from their Coast Guard C130 eruptive activity of Carlisle volcano. Steam with some ash was being emitted from summit vent and was rising to about a 2,500 m altitude. The light colored plume trailed to ENE for up to 30 km."
