918 FLORAL ZONES OF THE POTTSVILLE FORMATION. 



Sharp :Mountain, i. e., near the place of the Buck :Mountain l)ed, 

 whereas the outcrop of nearly the entire Pottsville formation, in its 

 full thickness, including- both of the groups of Lykens coals, extends 

 from near Fishing- Creek Gap nearly to the Big Flats, a distance of 

 over 17 miles along the south face of Sharp Mountain, quite outside 

 of the ••approximate boundary of the lowest Lykens coal" and partly 

 within the territory represented on the anthracite maps of the recent 

 State geological survey as Mauch Chunk red shales.
