Its near perfect shape gave rise to many legends about the volcano among the peoples of the region, such as the Itelmens and Kuril Ainu. The Russian scientist Stepan Krasheninnikov was told the story that it was once a mountain in Kamchatka, but the neighbouring mountains became jealous of its beauty and exiled it to the sea, leaving behind Kurile Lake in southern Kamchatka. Geographically, this story is not without evidence, as after the last Ice Age most of the icecaps melted, raising the world's water level, and possibly submerging a landbridge to the volcano.
