Contains 165 maps.

Units were mapped in the following stratigraphic sequences: the Carbondale and most of the Lisman Formations of western Kentucky; the Linton, Petersburg, Dugger, Shelburn, West Franklin, and Ditney Formations of Indiana; the Carbondale, Modesto, and Bond Formations of Illinois; the upper part of the Cherokee Group and the Marmaton, Pleasanton, Kansas City, Lansing, and Shawnee Groups of Missouri, Iowa, eastern Kansas and southeastern Nebraska; and the upper part of the Cabaniss Group and the Marmaton, Skiatook, and Ochelata Groups of northeastern Oklahoma...
