Day  Two: South Cove/Cape Arago
The rocks at Cape Arago have been tilted and
faulted.  To the left, Melinda trying to show 
Cami, Nate and Karim how to get a strike and
dip measurement using a Brunton compass.

The various coves and bays in the area are 
the result of erosion along fractures and
faults.  In the figure above, I've stuck little
red dots on two sandstone layers that are
offset along a fault.  Cami Idzerda's picture
of the same fault (upper right) shows that
erosion preferentially occurs along the faults,
leaving linear channels and tidepools in the
wave-cut platform.  The picture to the
right shows that there is a series of fractures/
faults, rather than one single one, and also
shows the long water filled channels that
result.
