Summary:
Name Levias, with type locality just east of town of that name in Crittenden Co., KY, is now proposed for uppermost member of the Ste. Genevieve, between Rosiclare sandstone below and Renault formation above in western KY and adjacent IL. Replaces "Lower Ohara" of Butts and Ulrich. Ohara, as originally defined should not be considered a stratigraphic unit because it transgresses an important unconformity. The part that has been termed "Upper Ohara" is equivalent to the Renault of IL. Name Ohara is rejected as it has been made useless by nearly 30 yrs of misinterpretation.

Summary:
Levias and Spar Mountain Members of Ste. Genevieve Limestone are no longer used in Indiana. Usage of the Ste. Genevieve of the Blue River Group in Indiana is here revised. In the subsurface, unit is divided into (ascending) Fredonia, Karnak, and Joppa Members, which are basically equivalent to members of the same name in IL. This nomenclature replaces that of Shaver and others (1986) as the IN State usage. In outcrop, Joppa is replaced by rocks typical of upper Karnak. Uppermost rocks of the Ste. Genevieve on the surface and in the very shallow subsurface are assigned to the Bryantsville Breccia Bed of the Karnak Member. Bryantsville of previous usage marked the top of the Levias Member. [Indian Creek Limestone Beds not discussed.]
