From Byers and Brannock (1949): "In the summer of 1946 a column of steam 4000 feet high rose from the crater. According to R. R. Coats (personal communication), who visited the 1945 crater dome in June 1946, steam and strongly pungent gases were escaping from beneath the shattered carapace of the dome. He did not see the orifice of the main large fumarole near the center of the dome because of the great difficulty in traversing the blocky lava. According to Frank S. Simons (personal communication) the melting snow around the crater had a distinct sour taste late in the summer of 1946."
From Simons and Mathewson (1947):"[A] small smoke cloud [from Great Sitkin] was visible from Adak Island on August 14, 1946."`
