Port Hueneme, California in the context of "Santa Barbara Channel"

Anacapa Island (Chumash: Anyapax, meaning "mirage, illusion") is a small volcanic island located about 11 miles (9.6 nmi; 18 km) off Port Hueneme in Ventura County, California. The island is composed of a series of narrow islets 6 mi (10 km) long, oriented generally east–west and 5 mi (8 km) east of Santa Cruz Island. The three main islets, East, Middle, and West Anacapa, have precipitous cliffs, dropping off steeply into the sea.

Anacapa is the smallest of the northern islands of the Channel Islands archipelago, and is within the Channel Islands National Park. It is 9 miles (7.8 nmi; 14 km) across the Santa Barbara Channel from the nearest point on the mainland. It lies southwest of the city of Ventura, California. The northern waters of Anacapa Island are protected by the Anacapa State Marine Reserve, which is one of the MPAs existing in the Channel Island National Park.

The Oxnard Plain is a large coastal plain in southwest Ventura County, California, United States surrounded by the mountains of the Transverse Ranges. The cities of Oxnard, Camarillo, Port Hueneme and much of Ventura as well as the unincorporated communities of Hollywood Beach, El Rio, Saticoy, Silver Strand Beach, and Somis lie within the over 200-square-mile alluvial plain (520 km). The population within the plain comprises a majority of the western half of the Oxnard-Thousand Oaks-Ventura Metro Area and includes the largest city along the Central Coast of California. The 16.5-mile-long coastline (26.6 km) is among the longest stretches of continuous, linear beaches in the state.

The high quality soils, adequate water supply, favorable climate, long growing season, and level topography are characteristic of the Oxnard Plain where the top cash crops are strawberries, raspberries, nursery stock and celery. Ventura County is one of the principal agricultural counties in the state and it is a significant component of the economy with a total annual crop value in the county of over $1.8 billion in 2014. There is strong public sentiment for retaining agricultural production, as reflected in the SOAR (Save Open Space and Agricultural Resources) initiatives that have been approved by voters.

Point Mugu (/muːˈɡuː/, Chumash: Muwu) is a cape or promontory within Point Mugu State Park on the Pacific Coast in Ventura County, near the city of Port Hueneme and the city of Oxnard. The name is believed to be derived from the Chumash Indian term "Muwu", meaning "beach", which was first mentioned by Cabrillo in his journals in 1542. Mugu Lagoon is a salt marsh just upcoast from the promontory within the Naval Base Ventura County formerly called the Naval Air Station Point Mugu.

The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now Kern, San Luis Obispo, Santa Barbara, Ventura, and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south to Mount Pinos in the east. Their territory includes three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source.

Modern place names with Chumash origins include Malibu, Nipomo, Lompoc, Ojai, Pismo Beach, Point Mugu, Port Hueneme, Piru, Lake Castaic, Saticoy, Simi Valley, and Somis. Archaeological research shows that the Chumash people have deep roots in the Santa Barbara Channel area and have lived along the southern California coast for millennia.
