CONEMAUGH FORMATION IN WEST VIRGINIA 215 



sandstone has been replaced by shale, is equivalent to the Conemaugh 

 and Monongahela formations and in some places may include a portion 

 of the Dunkard. 



Westward from the Kanawha river to the Ohio and in Putnam and 

 Cabell counties the surface formation for the most part is evidently Cone- 

 maugh, but no details are available at present for closer description. 

 There are many records of oil borings in Cabell, but in the absence of 

 surface measurements they can not be connected up with the eastern 

 localities. At Central City, on the Ohio, the Pittsburg coal bed is 340 

 feet above the river, but exposures are rare. The Ames limestone with 

 all its characteristic features is present near Huntingdon and the Cam- 

 bridge limestone is seen below Central City.* 



Beyond the Kanawha, in southwestern West Virginia, one finds the full 

 section of the Conemaugh only in Putnam county near Raymond, but the 

 lower beds extend southward into northern Raleigh and apparently even 

 into southern Mingo, so that they should be found in Pike county of 

 Kentucky; but there are few details given in any of the reports. 



Mr Campbell finds two coal horizons in Putnam county, one at 50 feet 

 above the top of the Charleston sandstone and the other 300 to 400 feet 

 higher. At Griffiths ville, in eastern Lincoln, a coal is mined which he 

 refers to the lower horizon. Mr dTnvilliers measured on Cobbs creek 

 in this portion of Lincoln: 



Feet 



1. Shales, sandstones and some red beds 150 



2. Massive sandstone 25 



3. Concealed, sandstone and red shale 150 



4. Shales and stiff clay slates 75 



5. Coal bed 6 



This seems to be Conemaugh above the coal bed, which has been taken to 

 be the Upper Freeport. Mr d'lnvilliers's section in northern Raleigh 

 has been given ; it seems to show that a considerable part of the Cone- 

 maugh remains even there. 



Doctor White finds the Ames limestone in the northwestern part of 

 Wayne county, and at 3 miles from the mouth of Twelve-pole creek what 

 appears to be the double Cambridge limestone is shown overlying the 

 Kentucky Coal bed 10, which is only a few feet above the Buffalo sand- 

 stone. This limestone is shown frequently along the Big Sandy river 

 from the mouth southward to Big Blaine creek, in Lawrence of Ken-
