Description: From Grewingk (1850, translated 2003 by Fritz Jaensch): "In Sauer (Billings's exped. [Sauer, Eng. Ed., London, 1802, p. 164]) it states: '[The terrain of Unimak Island] is high, broken, and rugged, and there are three very conspicuous mountains upon it. The summit of the first [Pogromnaia?] is very irregular; the second [Shishaldin] is a perfect cone towering to an immense height, and discharging a considerable body of smoke from its summit [19 April 1790]; the third (Khaginak) has its summit apparently rent and broken, covered with snow, and towering above the fog which covered the middle of the land.' Sarichev (II, pp. 28-29, with two profiles) sighted the three sugarloaf-shaped mountains on the eighteenth of June 1790. He named them Agayedan (Shishaldin), Khagman (Khaginak), and Kugidahk-Yagutcha (Pogromnaya). The first of them was smoking; the second had the appearance of a caved-in cone."

The English translation of Sarychev states that on June 17, 1790, at ten o'clock, "we discovered the conical summits of the island of Unimak, one of which, called Agagedan, is likewise volcanic, and at that time emitted a thick smoke."
