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/3043/.  ArcInfo export files and ArcView 
shapefiles may be extracted from a zip-compressed file (SIM3043.zip).  
In addition, an Adobe Portable Document Format (PDF) file (SIM3043.pdf) can be 
downloaded, from which paper copies may be printed.

The data were compiled from field mapping.  Michael Machette (USGS) and Robert 
Kirkham (CGS) reviewed the geologic map. Geologic names were reviewed by T. W. 
Judkins (USGS).

This geospatial database consists of ArcInfo export files (.e00) and ArcView 
shapefiles contained in a zip archive.  Compressed archive file contains both 
types of geospatial database files.  See the list below.  Please refer to the 
file sim3043.met for detailed metadata documentation for this geospatial database.

In order to conform to naming limitations of shapefile format, coverage names 
were changed before conversion to shapefiles. Therefore standard item names in 
shapefiles match shapefile names, not coverage names as described in metadata 
document.  The prefix "elkhorn" was dropped from all files and a suffix 
indicating feature type was added ("_arc", "_point", "_label", or "_polygon") for 
conversion of coverages to shapefile format.
