Transverse Ranges Geomorphic Province
Transverse Ranges are an east-west
trending series of steep mountain
ranges and valleys. The east-west
structure of the Transverse Ranges is
oblique to the normal northwest
trend of coastal California, hence
the name "Transverse." The
province extends offshore to include
San Miguel, Santa Rosa, and Santa
Cruz islands. Its eastern extension,
the San Bernardino Mountains, has
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 oilproducing
areas in the United States.
