The contact is very marked where the Medina is cross-bedded. It looks as if there is here 8 to 9 feet of thin bedded Clinton followed by the heavy bed which is here only 4 1/2 feet thick. Rocheata. Rests with sharp contact on the departed of Clinton. The latter is a hard gray crystalline limestone followed without transition by the Rocheata hardened blue shales, reptile with the regular gypsum. There may be 26 feet of Rocheata.
