Natural islands in San Pedro Bay include
Terminal Island (actually an augmented
mudflat and Rattlesnake Island), the site of much of Los Angeles' and Long Beach's port facilities,
Mormon Island, the site of an abortive settlement attempt by
San Bernardino-based Mormon pioneers in the 1850s, and Smith's Island.
Land reclamation operations by Los Angeles have considerably enlarged Terminal Island, as well as linking Mormon Island to the mainland.
Deadman's Island sat at a landmark at the foot of the bay, but was removed in 1928 as part of the effort by
Phineas Banning and his successors to enlarge the harbor. In 1927 an airport, originally called
Allen Field and later
Naval Air Station Terminal Island, was built on San Pedro's Terminal Island. Four small artificial islands containing
oil wells (the
THUMS Islands) are scattered around the bay near Long Beach. The oil drilling equipment itself is masked by tropical landscaping, architectural features and fake high-rise "buildings" in an attempt to improve their appearance from shore. These islands, named Oil Islands Freeman, Grissom, White, and Chaffee, are named for
Theodore Freeman, the first
NASA astronaut to die during flight, and for
Gus Grissom,
Ed White, and
Roger B. Chaffee, who were killed by a fire during the
Apollo 1 mission. ==Free Harbor Fight==
