California

California is a state located on the west coast of the United States. It is the most populous state in the U.S., as well as physically the most diverse, with the highest and the lowest points in the lower 48 states located within 150 miles of each other. If California were an independent nation, it would have the fifth largest economy in the world (see economy of California). The state's official nickname is "The Golden State" in reference to California's 1849 Gold Rush. {{ref|origin_of_nickname}} California's U.S. postal abbreviation is CA, and its Associated Press abbreviation is Calif.

Geography

California borders the Pacific Ocean, Oregon, Nevada, Arizona, and the Mexican state of Baja California. The state has strikingly beautiful natural features, including an expansive central valley, tall mountains, hot deserts, and hundreds of miles of scenic coastline. With an area of 410,000 km² it is the third largest state in the U.S. Most major cities cling to the cool seacoast along the Pacific, notably Los Angeles, San Francisco, San Jose, Santa Ana/Orange County, and San Diego. However, the capital, Sacramento is in the Central Valley.

California has extremely varied geography. In the center of the state lies the Central Valley, a huge, fertile valley bounded by the coastal mountain ranges in the west, the granite Sierra Nevada to the east, the volcanic Cascade Range in the north and the Tehachapi Mountains in the south. Mountain-fed rivers, dams, and canals provide water to irrigate the Central Valley. With dredging, several of these rivers have become sufficiently large and deep that several inland cities, notably Stockton, California, are seaports. The hot, fertile Central Valley is California's agricultural heartland and grows a large portion of America's food.

In the center and east of the state are the Sierra Nevada, containing the highest peak in the contiguous lower 48 states, Mount Whitney, at 14,505 feet (4421 m). Also located in the Sierra are the world famous Yosemite National Park and a deep freshwater lake, Lake Tahoe, the largest lake in the state by volume. To the east of the Sierra are Owens Valley and Mono Lake, an essential seabird habitat. To the west is Clear Lake, California's largest freshwater lake by area. The Sierra Nevada, very high in elevation, are the only part of California that receive arctic temperatures in the winter.

In the south lie the Transverse Ranges and a large salt lake, the Salton Sea. The south-central desert is called the Mojave. To the northeast of the Mojave lies Death Valley, which contains the lowest, hottest point in North America. The lowest point of Death Valley and the peak of Mount Whitney are less than 200 miles apart. The hiking trek between the two points has been attempted, several times, most notably by Lee Bergthold. Indeed, almost all of southeastern California is arid, hot desert, with the Coachella Valley routinely experiencing extreme high temperatures during the summer.

Finally, along the densely-populated but long California coast lie a number of major metropolitan areas, including San Francisco Bay, Los Angeles, and San Diego. Climates near the Pacific Ocean are remarkably moderate compared with inland climates. Winter temperatures never reach freezing (snow is unheard of) and summer temperatures rarely reach above the high 80's Fahrenheit.

California is famous for its earthquakes, due partly to the presence of the San Andreas Fault. While more powerful earthquakes in the United States have occurred in Alaska and along the Mississippi River, California earthquakes are notable in their frequency and location in highly populated areas. Some people believe, eventually, a huge earthquake will result in the splitting of coastal California from the continent, either to sink into the ocean or form a new landmass. The fact that this scenario is completely implausible from a geologic standpoint does not lessen its acceptance in public conventional wisdom, or its exploitation by the producers of science fiction and fantasy media. Notable movies in which the possible destruction of much of California by an earthquake includes the titles Earthquake, A View to a Kill, Escape from L.A. and Superman.

California is also home to several volcanoes, some active such as Mammoth Mountain. Other volcanoes include Lassen Peak, which erupted from 1914 and 1921, and Mount Shasta.

Climate

Different regions of California have very different climates, depending on their latitude, elevation, and proximity to the coast. Most of the state has a Mediterranean climate, with rainy winters and dry summers. The influence of the ocean generally moderates temperature extremes, creating cooler summers and warmer winters, and the cold oceanic California Current offshore often creates summer fog near the coast. As one moves away from the coast, the climate becomes more continental, with hotter summers and colder winters. Westerly winds from the ocean also bring moisture, and the northern parts of the state generally receive higher rainfall than the south. California's mountain ranges influence the climate as well: moisture-laden air from the west cools as it ascends the mountains, dropping moisture; some of the rainiest parts of the state are west-facing mountain slopes. Northwestern California has a temperate climate with rainfall of 15–40 inches (400–1000 mm) per year. The Central Valley has a Mediterranean climate, but with greater temperature extremes than the coastal areas; parts of the valley are often filled with thick fog, similar to that found in the coastal valleys. The high mountains, including the Sierra Nevada, have a mountain climate with snow in winter and moderate heat in summer.

On the east side of the mountains is a drier "rain shadow." California's desert climate regions lie east of the high Sierra Nevada and southern California's Transverse Ranges and Peninsular Ranges. The low deserts east of the southern California mountains, including the Imperial and Coachella valleys and the lower Colorado River, are part of the Sonoran Desert, with hot summers and mild winters; the higher elevation deserts of eastern California, including the Mojave Desert, Owens Valley, and the Modoc Plateau, are part of the Great Basin region, with hot summers and cold winters.

Death Valley, in the northern portion of the Mojave Desert on the east side of the state, is the hottest spot on the Western Hemisphere, with high temperatures over 120 °F common in the summer. The highest temperature in the Western Hemisphere, 134 °F (56.6 °C), was recorded in Death Valley on July 10, 1913. Temperatures of 130 °F or higher have been recorded as recently as 2005.
