A unit used in Ohio and Kentucky to represent generally unfossiliferous or poorly fossiliferous facies in the uppermost type Cincinnatian. In Ohio and parts of Kentucky, the Drakes consists of red terrigenous mudstones, probably peritidal in origin and belonging to the C6 sequence (Preachersville Member). In central Kentucky, the Drakes also includes dolomitic peritidal facies of the C4 sequence (Rowland Member), fossiliferous, commonly coral-bearing shallow subtidal strata of the C5 sequence (Bardstown Member), the distinctive gastopod coquinas of the C5 sequence (Marble Hill Member), and the dolomitic peritidal facies of the C5 sequence (Saluda). In general, the facies relationships of the uppermost type Cincinnatian are the most poorly known in the entire Cincinnatian. In central Kentucky, the Drakes overlies the Ashlock Formation; in northern Kentucky and Ohio, the Drakes overlies the Bull Fork Formation.
