Silt and clay are McNairy Formation. This unit corresponds to the “silt and sand deposits” in north as southern Illinois near the end of the Cretaceous Period (Potter UNIT SYSTEM mostly mottled brownish gray and massive to indistinctly bedded; they Kentucky on the map of Finch (1967). and Pryor 1961). The McNairy rests either on the Post Creek Formation valleys uplands valleys uplands THICKNESS (FEET) contain lenses of sand and gravel. Gravel consists dominantly of chert with a gradational contact or on bedrock with an erosional contact.
