The Lava City Roller Dolls are 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, the Cinder Kittens, both compete across Oregon and throughout the entire western region. Real. Strong. Athletic. Revolutionary.
