IMPORTANT UPDATE INFORMATION ON NEW DATA FILES ON THIS CD.

The directory, New_Shapes, contains the same files as in the Arc_maps
directory but in shape file format. The shape file format is a 
nonproprietary format that can be directly used or imported buy various
GIS type software packages. A "g" at the end of the primary file name
denotes polygon geology, a "ga" denotes geology arcs, and a "f" denotes
faults.

The directory, New_Basedata, contains updated versions of 
the following Nevada base data layers. The directory for arc export
files is called E00_file. The directory for shape files is called 
Shapefiles. These 1:1,000,000 scale data layers were added after 
the first release of this CDROM and are not listed in the original 
documentation.
