The Volcanic Rock Festival was held yearly every summer in July from 1992-2003 out at a cinder cone near Mt. Bachelor, outside of Bend, OR. Started by Rachel Nordenhok in 1992, the festival had hundreds of acts perform over the years, most notably Floater in 1996, 1997 and 1998. Here are some pictures from Rachel's collection and the Stiff & Restless archives.
