THUMS Islands are a set of four artificial islands in San Pedro Bay off the coast of Long Beach, California. They were built to tap into the East Wilmington Oil Field. The landscaping and sound walls were designed to camouflage the operation and reduce noise, and they are the only decorated oil islands in the United States.
