Vortex I: A Biodegradable Festival of Life, more commonly known as just Vortex I, was a week-long rock festival in Oregon in 1970. It was sponsored by the Portland counterculture community, with help from the state of Oregon in Clackamas County near Portland. Held in order to demonstrate the positive side of the anti-War Movement and to prevent violent protests during a planned appearance in the state by President Richard Nixon, it remains the only state-sponsored rock festival in United States history.
