This Volcanoes Page is sponsored by the Keweenaw Volcano Observatory, and contains comprehensive information on volcanoes. Some of the descriptions, such as 'Ice volcanoes of Lake Superior's South Shore--Observations of a Chilling Phenomenon,' are geared towards a general audience, whereas other, more technical, pages are geared towards volcanologists. The pages contain JPEG images of eruptions, geologic interest pictures, and satellite photos.
