Sea, on the inner side of the Aleutian arc, is an unusual type of volcano, with pillar-like islands occasionally rising from the sea only to be in part or wholly destroyed by explosions. Since the earliest voyagers appeared in Bering Sea during the latter part of the eighteenth century, six islands have appeared, of which only three remain. These three peaks are now connected by sand bars and by the products of various volcanic explosions to form a single island.The formation of the first island, Ship Rock, was reported by the earliest navigators about 1768, and the rock was not washed away by the powerful wave-attack of the open ocean until 1888. Old Bogoslof, now known as Castle Rock, was pushed from beneath the sea in 1796 as a solid rocky mass 4,000 feet in diameter and 350 feet in height. New Bogoslof (Grewingk or Fire Island) appeared in 1883 on the other side of Ship Rock from Old Bogoslof.
The new island rose precipitously out of the sea to a height of over 800 feet, showing that it had been pushed out of an orifice in a very pasty condition instead of being formed of lava flows or ash which might accumulate around a crater.Between 1883 and 1906 many changes took place in the forms of both Old and New Bogoslof, but no other islands were formed until March, 1906. In this month an island 2,000 feet in diameter and 400 feet in height appeared between Old and New Bogoslof. The names Perry Peak and Metcalf Peak were both given to this rock. The sides of the mass were described as being quite smooth and the top had the form of a "broken horn" as if the whole mass had been forced through an opening in the top of the submarine volcano. In the winter of 1906-07 half of Perry Peak was blown away and another spinelike mass rose not far away from the shattered side of Perry Peak. The new rock, McCulloch Peak, was about the same size and had the same form as the original Perry Peak, and, like the latter, was destroyed by an explosion ten months after its appearance, in September, 1907. Since this time nothing appears to have been published concerning the evolution of the volcano, and it is the aim of this paper to present what little information has been procured from the reports of government vessels.1 I The early history of the volcano is described by C.
