Scientific Investigations Map 3133

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/3133/.  ArcInfo export files
and ArcView shapefiles may be extracted from a zip-compressed file (3133.zip).  In addition, an Adobe
Portable Document Format (PDF) file (SIM_3133.pdf) can be downloaded, from which paper copies
may be printed.

The data were compiled from field mapping.  Karl Kellogg (USGS), Alan VerPloeg (WyoGS) and
Richard Jones (WyoGS) reviewed the geologic map. Geologic names were reviewed by
Thomas 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 3133_meta.txt 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 "scp" 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.
