RIPLEY — OWL CREEK. 



87 



From this S. to Ripley, the Owl Creek marl is frequently found outcropping 

 in the branches tributary to the Hatchie, and in most wells. At Braddock's, S. 

 21, T. 3, R. 4 E.,fon Walnut Creek, the marl crops out without the overlying 

 limestone ; its thickness, as ascertained in wells, close at hand, is 18 feet — it 

 is underlaid by yellow, water-bearing sand. 



132. In the neighborhood of Ripley, there are numerous outcrops ; the 

 wells, also, have rendered the formation more accessible to study than is the 

 case elsewhere. The general features of the outcrops may best be studied at 

 an exposure in the S. portion of the town, at a bluff on the S. side of Tippah 

 Creek, where we obtain the following section :

 SECTION ON TIPPAH CREEK AT RIPLEY, TIPPAH COUNTY. 



Stratum No. 4 of this section is extremely variable, being frequently represen- 

 ted by a soft yellowish- white, calcareous sand, often associated with a soft yellow 

 limestone, teeming with corals (Ceriopora) and containing casts of shells with 

 loose nuclei (IT 128). It maybe studied to advantage in several outcrops E. of 

 Ripley, among others, at the bluff* above the crossing of Owl Creek on the Ripley 

 and Jacinto road. In several of these, as well as in others S. of Ripley on the 

 Pontotoc road, it may be seen overlaid by a black micaceous material, more or 

 less clayey, and containing a few poorly preserved shells. 



The locality on Owl Creek, 3 miles N. E. of Ripley, on S. 7, T. 4, R. 4, (first 

 visited by me in May 1856) where Dr. Spillman's fossils were obtained, forms 

 part of the bluff' mentioned above, which contains on the west side of Owl 

 Creek for several miles ; at the point mentioned it affords the following 

 section :
