Eden-like strata near Maysville, Kentucky, may be correlated with the Eden and lower Fairview formations of Cincinnati. To avoid the name Eden, which has stadial connotation, these rocks are included in the Kope formation, defined as medium-bedded limy shales (mean clastic ratio, 2.5 to 3.8) resting conformably between shaly Point Pleasant limestones (mean clastic ratio, 1.0) and unnamed shaly limestones (mean clastic ratio, 0.5).
