Digital databases are available for GIS users in ARC/INFO raster GRID

The data have been archived using tar, then compressed with gzip. File sizes (in parentheses) are for the gzip-compressed download file,
followed by the size of the file when uncompressed.

PLOTFILES
Plotfiles are available for those who wish to produce paper copies of
maps prepared from the digital data. These maps have been edited to conform
as much as possible to standard U.S. Geological Survey format for geologic
maps. The plotfiles are in PostScript format. Note that these plotfiles
are formatted to plot on 34 by 34 inch or larger sheets, so a large format
color plotter is required to produce a paper map. Alternatively, some software
can import PostScript files, allowing the user to manipulate the map image
as desired. Those who download plotfiles should also download the descriptive pamphlet.
To download the plotfile in PostScript format, select one of the following:
- Entire Region (16.8 MB, 371.4 MB) of98-625_5a.ps.gz
