*****greer.pdf is a graphic plotfile of the geologic map, as published, that can be read with Adobe Acrobat Reader 4. It will produce a plot that faithfully replicates the format, symbols, colors, and line work of a USGS full-color printed map (the actual published paper map is a 4-color offset-printed map). File size is 5.5 MB, page size at 100% is approximately 36" by 49" wide. Plot resolution, quality, and colors will vary with plotter, inks, and paper used.
