This geospatial database has been approved for release and 
publication by the Director of the USGS.  Although this database 
has been subjected to rigorous review and is substantially 
complete, the USGS reserves the right to revise the data 
pursuant to further analysis and review.  Furthermore, it is 
released on condition that neither the USGS nor the United 
States Government may be held liable for any damages resulting 
from its authorized or unauthorized use.

The database can be downloaded via the Web from 
http://pubs.usgs.gov/sim/2005/2890/.  ArcInfo export files and 
ArcView shapefiles may be extracted from a gzip-compressed tar 
file (2890.tar.gz) or zip-compressed file (2890.zip).  In 
addition, Adobe Portable Document Format (PDF) files can be 
downloaded for the map sheets, from which paper copies may be 
printed.
