THE COALBURG COAL. 



The Coalburg Coal of White 6 , belonging about 140 feet 

 below the top of the Pottsville, is not of minable thickness in 

 Lewis, where it crops, and was not definitely recognized in 

 borings where its horizon is underground. A black slate was 

 observed at this horizon on Fallen Timber Run, one-half mile 

 east of Bablin, at an elevation of 1135' B. It was also observed 

 on the Right Fork of the Little Kanawha, 0.6 mile southeast 

 of Wildcat, at an elevation of 1085' B. 



The following exposure, which seems to represent the 

 Coalburg Coal, but which may be the Mercer, was observed 

 along the Upshur Line:

THE LOWER COALBURG SANDSTONE. 



The Lower Coalburg Sandstone of Hennen and the 

 writer, 7 which is a great cliff rock in Logan and Mingo, com- 

 ing between the Coalburg and Winifrede Coals, is not promi- 

 nent in southern Lewis in the region of its crop. At the Bab- 

 lin road fork, a massive sandstone appears at an elevation of 

 1000' B. that may represent it.
