Generalized north-south stratigraphic cross section (datum on the V-shale) illustrates the regional extent and thickness of major Cherokee and Marmaton (Atokan-Desmoinesian) coals and other units through eastern Kansas from the Oklahoma to Nebraska borders. Evidence of earlier accommodation development in the Forest City basin is observed from older deposits including numerous coal seams underlying the Riverton coal. The Riverton coal is the oldest regionally continuous coal in eastern Kansas. Coals become thinner and less extensive over the Bourbon arch and thicker and more extensive northward into the Forest City Basin and south into the Cherokee Basin.
