California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of California about 7.1 miles driving distance from the United States Forest Service office in the Northern Californian city of North Fork, California.
Southern California is a geographic and cultural region that generally comprises the southern portion of the U.S. state of California. It includes the Los Angeles metropolitan area as well as the Inland Empire. The region generally contains ten of California's 58 counties: Imperial, Kern, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, San Luis Obispo and Ventura counties.
The Santa Cruz Mountains are a mountain range in central and Northern California, United States, constituting a part of the Pacific Coast Ranges. They form a ridge down the San Francisco Peninsula, south of San Francisco. They separate the Pacific Ocean from the San Francisco Bay and the Santa Clara Valley, and continue south to the Central Coast, bordering Monterey Bay and ending at the Salinas Valley. The range passes through the counties of San Mateo, Santa Clara, and Santa Cruz, with the Pajaro River forming the southern boundary.
The Pacific Coast Ranges are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although they are commonly thought to be the westernmost mountain range of the continental United States and Canada, the geologically distinct Insular Mountains of Vancouver Island lie farther west.
The Santa Monica Mountains is a coastal mountain range in Southern California, next to the Pacific Ocean. It is part of the Transverse Ranges. The Santa Monica Mountains National Recreation Area encompasses this mountain range. Because of its proximity to densely populated regions, it is one of the most visited natural areas in California.
The Transverse Ranges are a group of mountain ranges of southern California, in the Pacific Coast Ranges physiographic region in North America. The Transverse Ranges begin at the southern end of the California Coast Ranges and lie within Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside and Kern counties. The Peninsular Ranges lie to the south. The name Transverse Ranges is due to their east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.
The San Jacinto Mountains are a mountain range in Riverside County, located east of Los Angeles in southern California in the United States. The mountains are named for one of the first Black Friars, Saint Hyacinth, who is a popular patron in Latin America.
The Santa Rosa Mountains are a short mountain range in the Peninsular Ranges system, located east of the Los Angeles Basin and northeast of the San Diego metropolitan area of southern California, in the southwestern United States.
The San Rafael Mountains are a mountain range in central Santa Barbara County, California, U.S., separating the drainages of the Santa Ynez River and the Santa Maria River. They are part of the Transverse Ranges system of Southern California which in turn are part of the Pacific Coast Ranges system of western North America.
The Sierra Madre is a mountain range in southwestern California. It forms the southernmost part of the California Coast Ranges and lies mostly in Santa Barbara County, with a small portion extending into Ventura County. The Sierra Madre has a northwest-to-southeast orientation, bordered on the north and northeast by the Cuyama River and Cuyama Valley, and on the south and east by the drainage of the Sisquoc River.
The Laguna Mountains are a mountain range of the Peninsular Ranges System in eastern San Diego County, southern California. The mountains run in a northwest/southeast alignment for approximately 35 miles (56 km).
The Dead Mountains are a mountain range in the southeastern Mojave Desert, in San Bernardino County, California. The range borders the tri-state intersection of Nevada, Arizona and California, and the Mohave Valley, with the Fort Mojave Indian Reservation bordering the range foothills on the east and northeast, in the three states.
The San Emigdio Mountains are a part of the Transverse Ranges in Southern California, extending from Interstate 5 at Lebec and Gorman on the east to Highway 33–166 on the west. They link the Tehachapis and Temblor Range and form the southern wall of the San Joaquin Valley. The range is named after Emygdius, an early Christian martyr.
The Gabilan Range or Gabilán Range are a mountain range in the inner California Coast Ranges System, located in Monterey County and San Benito County of central California. Pinnacles National Park is located in the southern section of the range.
