    See also: History of Los Angeles

    Los Angeles County was one of the original counties of

    California, created at the time of statehood in 1850.[6] The

    county's large area included parts of what is now Kern County,

    San Bernardino County, Riverside County and Orange County.

    These parts of the county's territory were split to form San

    Bernardino County in 1853, Kern County in 1866, and OrangeCounty in 1889. In 1893, part of San Bernardino County became

    Riverside County.


    According to the 2000 census, the county has a total area of 4,752.32 square miles (12,308.5 km2), of which 4,060.87

    square miles (10,517.6 km2) (or 85.45%) is land and 691.45 square miles (1,790.8 km2) (or 14.55%) is water.[7] Los

    Angeles County borders 70 miles (110 km) of coast on the Pacific Ocean and encompasses towering mountain ranges,

    deep valleys, forests, islands, lakes, rivers, and desert. The Los Angeles River, Rio Hondo, the San Gabriel River and

    the Santa Clara River flow in Los Angeles County, while the primary mountain ranges are the Santa Monica Mountains

    and the San Gabriel Mountains. The western extent of the Mojave Desert begins in the Antelope Valley, in the

    northeastern part of the county. Most of the population of Los Angeles County is located in the south and southwest,

    with major population centers in the Los Angeles Basin, San Fernando Valley and San Gabriel Valley. Other population

    centers are found in the Santa Clarita Valley, Crescenta Valley and Antelope Valley.

    The county is divided west-to-east by the rugged San Gabriel Mountains, filled with coniferous forests and subject to

    plentiful snowfall in the winter. The San Gabriel Mountains are part of the Transverse Ranges of southern California,

    and are contained mostly within the Angeles National Forest. Most of the highest peaks in the county are located in the

    San Gabriel Mountains, including Mount San Antonio (10,068 ft) at the Los Angeles-San Bernardino county lines,

    Mount Baden-Powell (9,399 ft), Mount Burnham (8,997 ft), and the well-known Mount Wilson (5,710 ft) where the

    Mount Wilson Observatory is located. Several smaller, lower mountains are located in the northern, western, and

    southwestern parts of the county, including the San Emigdio Mountains, the southernmost part of TehachapiMountains, and the Sierra Pelona Mountains.
