Named the Whitewater beds of the Richmond group for the Whitewater River, at Richmond, Wayne Co., southeastern IN. Unit also recognized in southwestern OH. Consists of brownish or yellowish (sometimes bluish), thin-bedded limestone and shale. Unit has a nodular appearance. Thickness is 45 to 50 ft. Overlies the Liberty beds and underlies the Madison [Saluda] formation. The Whitewater is of Late Ordovician age.

The Geological Survey of Ohio recognizes the Cincinnati Group proposed by Meek and Worthen (1865), but at this time retains it as an informal term. The unit will be formally reinstated as a lithostratigraphic term after revision of its lower boundary and minor lithologic redescription of its units are completed. The ten formations included in the group are the (ascending) Clays Ferry Formation, Kope Formation, Fairview Formation, Miamitown Shale, Grant Lake Limestone, Arnheim Formation, Waynesville Formation, Liberty Formation, Whitewater Formation, and Drakes Formation. Six members have been identified in the course of field mapping: the Point Pleasant Tongue of the Clays Ferry, the informal Bellevue, Corryville, Mount Auburn, and Straight Creek members of the Grant Lake Limestone, and the Preachersville Member of the Drakes Formation. The Backbone Creek and Elk Creek beds are recognized as excellent stratigraphic marker beds.

The Whitewater Formation in southeastern IN consists of interbedded thin-bedded, argillaceous, fossiliferous limestone, thin-bedded ostracodal limestone, medium-bedded, relatively unfossiliferous limestone, rubbly weathering, argillaceous limestone, and shale. Fossils include brachiopods, bryozoans, and mollusks. Overlies the Saluda Formation and unconformably underlies the Silurian Brassfield Formation. The Whitewater is of Late Ordovician (Richmondian) age.

The Cincinnatian Series is divided into five depositional sequences in this report, which correspond to lithostratigraphic units. The following stratigraphic names in KY should be abandoned as they have been applied to bodies of rock already named in downramp areas of OH and IN: Bardstown (=lower Whitewater), Reba (=Oregonia), Stingy Creek (=Mount Auburn), Calloway Creek (=Bellevue), and Clays Ferry (=Fairview). The following units in KY, OH, and IN lump dissimilar facies and straddle sequence boundaries and therefore should be abandoned: Drakes, Ashlock, Dillsboro, Tanners Creek, and Bull Fork. Grant Lake has been defined in several different ways and consequently should be abandoned. Several units will be redefined at a later date, including the upper part of the Whitewater and the "Sunset" and "Saluda" of OH and IN. Formal naming of new lithostratigraphic units will follow further study.

Age of Whitewater Formation is refined to Cincinnatian (Richmondian).
