Comments	in western Kentucky the unit thicknesses range as follows: the Kincaid Limestone (0-65 m), the Degonia Sandstone (1.5-12 m), the Clore Limestone (20-40 m), the Palestine Sandstone (9-22 m), the Menard Limestone (15-45 m), the Waltersburg Sandstone (6-25 m), the Vienna Limestone (0-12 m), the Tar Springs Sandstone (20-35 m); in west-central Kentucky unit thicknesses range as follows: the Leitchfield Formation (0-380 m) which includes the Buffalo Wallow Formation (0-270 m) and the Tar Springs Formation (0-130 m). In the Buffalo Wallow Formation, the Kinkaid Limestone Member ranges from 0-60 m thick and the Vienna Limestone Member ranges from 0-10 m thick.
Stratigraphic units	Includes the Leitchfield Formation, Buffalo Wallow Formation, and Tar Springs Formation in west-central Kentucky and the Kinkaid Formation, Degonia Sandstone, Clore Limestone, Palestine Sandstone, Menard Limestone, Waltersburg Sandstone, Vienna Sandstone, and Tar Springs Sandstone in western Kentucky
