     Baja California, Mexico is a very long peninsula with the Gulf of California to the East and the Pacific
Ocean to the West.  It is mostly a desert area with a couple of tourist sites.  We hear about it only when
it is hit by a hurricane or if there is an endurance race.  Geologically, it is of great importance because it is
moving to the Northeast and slamming into California and creating the dangerous San Andreas fault.

     In this view the peninsula has been rotated counter-clockwise in order to fill the viewing frame.  It looks
quiet and rocky.




     In this view, circular features on the Baja California peninsula are highlighted by using the measuring
tool that is packaged with Google Earth as a drawing tool.  The circular features represent volcanoes and
intrusions.  As you can see, volcanism is a dominant geologic process.

     Google Earth can also be used to study the pattern of linear features.

     There does not seem to be any regional patterns, just circular patterns associated with volcanism.
