Hollister Map showing Calaveras fault
This map is courtesy of
the US Census bureau Tiger map server. Click on the map to bring up the
(unannotated) original under their map ``browser''. From there try
interactively zooming out to see this map ``in context''.
The red letters indicate
the various stops on the walking tour. At each stop, a subset of this map will
be shown at four times this scale. On those close-up maps, the white numbers on
blue dots show where the corresponding photo was taken from; the blue arrows
show the direction the camera was pointed. If there is no arrow, the camera was
pointed down!
If I skip a number it's
because it nearly repeats one that is shown.
On the map above, the
black arrows indicate the sense of the fault's motion. The fault moves like
your hands do when you rub them against each other. The coast of California is
not ``falling off''; it is moving North laterally, in splinters! It's not just
the coast, either: although most of the Northward motion does happen West of
the San Andreas, the influence of the Pacific Plate dragging the Western edge
of the continent North can be felt all the way East to the Wasatch fault in central
Utah. (The Wasatch fault runs through Salt Lake City.)
