This is a vector data set.
The map projection used is Transverse Mercator.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 1
Ordinates (y-coordinates) are specified to the nearest 1
Planar coordinates are specified in Meters
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.

Constance J. Nutt mapped the geology from 1993 to 1997. Map was digitized by and ARC/INFO database created by Tracey Mercier, Clark Woodward, and Nancy Shock. Database structure checked by Nancy Shock. Norma J. Maes prepared the Adobe Illustrator map layout, which was used for the printed paper map and gif and pdf plot and browse graphic files. F.C. Brunstein edited the geologic map and the Illustrator layout and prepared the metadata.
