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.



A closer view of linear features found in the northern end of Baja California. There does
not seem to be any regional patterns, just circular patterns associated with volcanism.
