The Pasadena orogeny is a major Late Quaternary-modern event of mountain formation, which took place in the middle or perhaps late Pleistocene or to the present-day. It is also known as the Coast Ranges orogeny or considered to be part of the Cascadian orogeny or Alpide Orogeny. Finally, the term Pasadena orogeny is sometimes applied to all very recent orogenies around the Pacific Ocean. The type location is close to Pasadena, California in the Transverse Ranges, and originally referred to the fast rise of the San Gabriel Mountains recorded there.
