Solid blue limestone layer i ft. 2 in. 
Nodular argillaceous limestone with Clitamhonites . 6 ft. 6 in. 
Thin limestone layers interbedded with a greater quantity of clay, not 
measured, approximately 40 ft. 
Top of Cynthiana formation. 
The clays overlying the Cynthiana formation carry an exten- 
sion of the Fulton fauna. The extensive exposures at the Tunnel 
cut overlie the Clitambonites horizon. The relation between 
the Clitambonites horizon at Carlisle and that at Rogers Gap has 
not been determined.
