THE DIGITAL GEOLOGIC MAP OF COLORADO IN ARC/INFO FORMAT

By Gregory N. Green

1992

Open-File Report OF-92-0507

****NOTE*** The files currently in the report were created in 1996 and 1997.  
They are in Arc format, and the .txt and other files were designed to be read 
in Arc Catalog.  They may not properly open otherwise. The e00 files also 
contain files that can only be read in Arc.  The original colorado.tar.gz 
file is a compressed tar file that contains all of the files that are now in 
the files OF92_0507.zip and Data_OF92_0507.zip.  This was done because it may 
be problematic for some users to extract the files from the older colorado.tar.gz file.

While the files were rezipped in 2009, users are cautioned to remember that 
the files were created in 1996 and 1997.

Open-File Report OF-92-0507 is preliminary and has not been reviewed for conformity.
