Geological Survey Open-file Report 01-179, version 1.0,

The SHAPE directory contains--for selected ArcInfo
coverages from the DATA directory--shapefiles and copies of
projection (.prj), and metadata (.txt) files for use with
ArcView and other applications that read .shp format files.
Not all coverages could be converted to shapefiles because
of the file name and item name character limits. If a
coverage has more than one feature (for example polygons
and lines), only one feature may be provided as a
shapefile.  Images and grids are not available as
shapefiles. The subdirectories are

backscat quadrangle index coverage
basemaps base map layers
battopo  elevation contours
geology  geologic map data
navigatn navigation and other location data
samples  sample locations and analyses
shaderel no shapefiles
