contain .e00 files, shapefiles, and pdf files of the map's illustrations
and correlation diagram, and pdf files of the map unit descriptions and
sources of information.  An ARC/INFO aml, keyfiles and shadeset
are included to produce the plot of the data.

	geo_net--map unit polygons and open water; lines that are geologic
		contacts and shorelines
