A crew cleans oil from the beach at Refugio State Beach on May 20, 2015 north of Goleta, California. About 21,000 gallons spilled from an abandoned pipeline on the land near Refugio State Beach, spreading over about four miles of beach within hours. The largest oil spill ever in U.S. waters at the time occurred in the same section of the coast where numerous offshore oil platforms can be seen, giving birth to the modern American environmental movement.
