Grewingk (1850, translated 2003 by Fritz Jaensch) states that Sarychev passed Gareloi on the twenty-fourth of September, 1790 and on June 17, 1791 and described Gareloi as a "very tall, snow-covered, fire-belching mountain." It is uncertain if an eruption was observed on either or both of these occasions. The English translation of Sarychev (translated from Russian in 1806 and 1807, republished 1969) makes no mention of "fire-belching" and instead simply states that Gareloi was covered in "eternal snow." Coats (1950): reports minor explosive activity at Gareloi in 1790. Petroff (1884), Becker (1898), and Dall (1870) make no mention of this dubious eruption.
Sauer's account (1802) of the same voyage that Sarychev was on does mention Gareloi on the 24th of September, 1790, and June 17, 1791, but makes no mention of volcanic activity.
