This map was prepared as a collaborative effort with the Missouri Division of Geology and Land Survey, the Kansas Geological Survey, and the Nebraska Conservation and Survey Division.
William H. Langer and David Smith mapped the geology in 1993 and 1994. The authors' team digitized the map and prepared the ARC/INFO database. Database structure checked by Nancy Shock, and she prepared the files for importing into Adobe Illustrator. Norma J. Maes prepared the Adobe Illustrator map layout, which was used for the on-demand paper map and gif and pdf plot and browse graphic files. F.C. Brunstein edited the publication and prepared some of the files for the Illustrator layout, and prepared the metadata file, which was checked by Nancy Shock.
