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/2005/2860/.  ArcInfo export files and 
ArcView shapefiles may be extracted from a gzip-compressed tar 
file (2860.tar.gz) or zip-compressed file (2860.zip).  In 
addition, Adobe Portable Document Format (PDF) files can be 
downloaded for each map sheet and the pamphlet, from which paper 
copies may be printed.

The data were compiled from field mapping and published geologic 
map sources.  Karl Kellogg, U.S. Geological Survey, and 
Catherine McDonald, Montana Bureau of Mines and Geology, 
reviewed the geologic map.

This geospatial database consists of ArcInfo export files (.e00) 
and ArcView shapefiles contained in a gzipped tar archive or zip 
archive.  Both compressed archive files contain both types of 
geospatial database files.  See the list below.  Please refer to 
the file 2860.met for detailed metadata documentation for this 
geospatial database.  For the most accurate color rendition when 
printing, please specify the Adobe RGB monitor profile.
