WEST VIRGINIA GEOLOGICAL SURVEY. 133 



LOCAL SECTIONS, CONEMAUGH SERIES. 



Besides the long sections in Chapter IV, embracing the 

 rocks of the several series, many of which show the Cone- 

 maugh, three local sections were made in Lewis giving addi- 

 tional exposures of this series. 



The following section was made with aneroid descending 

 the steep hillside east of the West Fork River at Jackson Mill. 

 Since the strata below the trolley grade were obscured by the 

 fill, formations 10-13, inclusive, of the section were supplied 

 from outcrops one-fourth mile southward, checked by a mea- 

 sured interval from the Ames Shale in the hill above : 



Jackson Mill Section, Hackers Creek District. 



The following section was made descending a hill road, 

 west of Leading Creek, and about midway between Alum 

 Bridge and Camden : 



Section 2.5 Miles Northeast of Alum Bridge, Freemans Creek 

 District.
