Chain of islands, southern California, U.S. Extending 150 mi (240 km) along and 12 – 70 mi (20 – 115 km) off the coast, it is divided into the Santa Barbara group (San Miguel, Santa Rosa, Santa Cruz, and Anacapa) and the Santa Catalina group (Santa Barbara, San Nicolas, Santa Catalina, and San Clemente). The islands range in size from Santa Cruz (98 sq mi [254 sq km]) to the small Anacapa islets. Rugged and mountainous, they are frequented by colonies of sea lions, seals, and birds and are noted for their distinctive plant life (several hundred varieties). The larger islands support sheep and cattle ranches, and Santa Catalina is a noted resort. Channel Islands National Park (established as a national monument in 1938) embraces Anacapa, San Miguel, Santa Barbara, Santa Cruz, and Santa Rosa.
