Description: Military pilots documented many observations of Shishaldin Volcano during 1954. A summary of their observations follows: Jan. 4: Steam rising from peak crater only, to 100ft above peak, dispersing to N. Several burned-off streaks along slopes but no evidence of recent ash or lava activity. Three small orifices in crater showed fire from close aerial range; Jan. 5: Small light grey smoke rose from peak, dispersing to SE. No visible activity other than this single small column; Jan. 8: Steam or light smoke rising from peak only. Usual evidence of hot ashes along N slope where snow is darkened. Wind blew the smoke straight off the peak; Jan. 14: Steam or light smoke filling entire crater rising 25-50 ft in the air. Single spire of steam or light smoke extended several miles to the NW from the peak; Jan. 16: Continuous flow of smoke coming from summit towards N. No lava. Smoke clung to and drifted down N side of mtn. Smoke visible from as far away as Pavlof; Feb. 12: Very small steam coming from summit. Ash on NW side. No lava; Feb. 22: Small steam and smoke rising to SE, ash covered SE side. No evidence of lava; Apr. 5: Heavy steam from crater only; May 21: Steam rising 100 ft from central crater; June 3: Some steam coming out of top of volcano crater; July 16: Heavy brown-black smoke rising to 13,000 ft. Lava running down slope. Smoke rising to 13,000 ft from base on N side; Aug. 14: Considerable steam coming out of the top of the crater. Steam drawn out about a mile horizontally before dissipating to the north; Oct. 31: Steady steam from peak
