[[Southern California]] is separated from the rest of the state by the east–west trending [[Transverse Ranges]].  The Transverse Ranges include a series of east–west trending mountain ranges that extend from Point Conception, at the western tip of Santa Barbara County, eastward (and a bit south) to the east end of the San Jacinto Mountains in western Riverside County.

The Santa Ynez Mountains make up the westernmost ranges, extending from Point Conception to the Ventura River just west-northwest of Ojai in Ventura County.  Pine Mountain Ridge, Nordhoff Ridge–Topatopa Mountains, Rincon Peak–Red Mountain, Sulphur Mountain, Santa Paula Ridge, South Mountain–[[Oat Mountain (California)|Oat Mountain]]–Santa Susana Mountains, Simi Hills, Conejo Mountains–Santa Monica Mountains are all part of the Western Transverse Ranges in Ventura and western Los Angeles counties.  The Transverse Ranges also include the [[Tehachapi Mountains]], which separate the Central Valley from the [[Mojave Desert]].

The Liebre Mountains occupy the northwest corner of Los Angeles County, and represent a northwestern extension of the San Gabriel Mountains, both on the Pacific plate side of the San Andreas Fault.  The fault divides the San Gabriel Mountains from the San Bernardino Mountains further to the east in San Bernardino County.

Urban Southern California occupies the valleys between the [[Santa Susana Mountains]], [[Santa Monica Mountains]] and [[San Gabriel Mountains]], which range from the Pacific Coast, eastward over {{convert|100|mi|km}}, to the [[San Bernardino Mountains]], north of [[San Bernardino, California|San Bernardino]].  The highest point of the range is [[Mount San Gorgonio]] at {{convert|11499|ft}}.  The San Gabriel Mountains have [[Mount Wilson observatory]], where the [[redshift]] was discovered in the 1920s.
