LIST OF REVISIONS (latest revision first):

May06 - color of unit afbm on the map of Quaternary deposits is corrected 
        to match that in the explanation and correlation diagram. (The
        color of afbm in the map originally released was that used for 
        unit alf.) This change makes the Quaternary deposits map version
        1.1 (v. 1.1), as noted on the face of the map (upper right). This 
        change has been made in both the Postscript and PDF versions of 
        the map, parts 5a and 5b (of06-1037_5a, of06-1037_5b), as well as 
        in the equivalent plotfile packages, parts 8a and 8b (of06-1037_8a, 
        of06-1037_8b). 
      - The name of the unzipped Postscript file containing the Liquefaction 
        Susceptibility Map (image) has been corrected to of06-1037_6a.eps. 
        This involves revision of the zipped equivalent of06-1037_6a.eps.zip
        and the Postscript plotfile package of06-1037_8a.zip.
      - The name of the unzipped PDF file containing the Liquefaction 
        Susceptibility Map (image) has been corrected to of06-1037_6b.pdf. 
        This involves revision of the zipped equivalent of06-1037_6b.pdf.zip
        and the PDF plotfile package of06-1037_8b.zip       
      - This revision list, now version 1.1, has been modified to reflect 
        these changes.
