Transverse Ranges Geomorphic Province
The San Gabriel and San Bernardino mountain ranges of southwestern California, and associated mountains and basins westward to the Pacific Ocean,
make up a unique east-trending geomorphic province known as the

the name "Transverse."
the Its eastern extension,
San Bernardino Mountains,
been displaced to the south along
the San Andreas Fault. Intense
north-south compression is
squeezing the Transverse Ranges.
As a result, this is one of the most
rapidly rising regions on earth.
Great thicknesses of Cenozoic
petroleum-rich sedimentary rocks
have been folded and faulted,
making this one of the important oil producing
areas in the United States.
