The Lava City Roller Derby is Bend's only all-female flat track roller derby league. Founded in February 2006, Lava City is a skater-run nonprofit and a proud, active member of the Women's Flat Track Derby Association since 2008. Lava City's travel teams, the Smokin' Ashes and the Spit Fires, and our junior derby team, all compete across Oregon and throughout the entire western region. Real. Strong. Athletic. Revolutionary.
