  This is an image generated from 2'x2' N/S surface deflections of the
vertical covering Puerto Rico and the Virgin Islands.  Some interesting 
features to note about this image are:

  Due to the mostly E/W nature of the geoid features in the area (which
yield mostly N/S deflections), the N/S deflections in this image are 
large, and obviously correlated with the location of the Puerto Rico trench
(in the North of the image) and the island of Puerto Rico itself (in the
middle of the image).  The turquoise color corresponds with the bottom of 
the trench, with magenta representing the northern face and red/orange 
representing the southern face of the trench.
