The Santa Monica Mountains stretch northwest of Santa Monica and Los Angeles down the coasts of California, east to west. With a broad number of minerals, including marine and non-marine sedimentary rocks and volcanic ash, the mountains are diverse in their geology. In addition, there are a huge number of folds and a collection of fossils in the field. The mountains are now starting to shift sitting near active faults. The mountains are not as old as others. Most of the rocks are from the Tertiary and Quaternary period, with most less than 20 million years old which is pretty young.
