Environmental Enlightenment #133

By Ami Adini - Reissued January 27, 2016

This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated terminology they have once learned, and enlighten the uninitiated on terms they may have heard but never known the meaning of.

Orientation: Los Angeles Basin

The Los Angeles Basin is the coastal sediment-filled plain located between the peninsular and transverse ranges (see further down) in southern California in the United States containing the central part of the city of Los Angeles. It is approximately 35 mi (56 km) long and 15 mi (24 km) wide, bounded by the Santa Monica Mountains, the Verdugo Mountains, and the Santa Ana Mountains. The Palos Verdes Peninsula, formerly an island, marks the outer edge of the basin along the coast.

 

The Peninsular Ranges are a group of mountain ranges which stretch 1500 km (900 miles) from southern California in the United States to the southern tip of Mexico's Baja California peninsula; they are part of the North American Coast Ranges that run along the Pacific coast from Alaska to Mexico. The Peninsular ranges run predominantly north-south.

The Transverse ranges are a group of mountain ranges of southern California, part of the North American Coast Ranges that run along the Pacific coast from Alaska to Mexico. The Transverse ranges run predominantly east-west, while the other coast ranges tend north-south. This is caused by a bend in the San Andreas Fault, which has pushed the mountain ranges up around it.

Some of the mountain and hill ranges in the Transverse Range include:
  • Santa Ynez Mountains
  • San Rafael Mountains
  • Sierra Madre Mountains
  • Santa Susana Mountains
  • Simi Hills
  • Santa Monica Mountains
  • San Gabriel Mountains
  • Puente Hills
  • San Bernardino Mountains
  • Tehachapi Mountains
  • You can find past issues of our "Environmental Enlightenment" at amiadini.com Wealth of information about environmental site assessments in the real estate transactions and issues concerning assessment and cleanup of contamination in the subsurface soil and groundwater.

    Call me if you have any questions. There are no obligations.
