7. Patton Creek Section. 



Feet. 



1. Limestone, generally light gray but sometimes bluish, 

 commonly pure but occasionally argillaceous or magne- 

 sian, heavy-bedded, with shaly partings, rare fossil im- 

 pressions 2 to 5 



2. Glossy black thinly laminated shale with ovid nodules 8 



3. Coal ih 



4. -'Soapstone" (fire-clay) 5 



The coal here was roughly estimated to be 20 feet above the 

 bottom of the channel of East Fork. 



About the mouth of Patton creek the exposures in the blufls of 

 both creek and river become more extensive. This locality was 

 examined nearly thirty years ago* by Prof. G. C. Broadhead, then 

 Assistant State Geologist, and an important section is recorded 

 in his report. t A part of this section, which was observed " at 

 Reese's coal-bed," was re-examined and verified, though the 13- 

 inch coal-seam is not now visible. The section is as follows : 



S. Broaclbeatl .Section. 



1. Limestone i' 



2. Bituminous shale 15" 



3. Bituminous coal 13" 



4. Slope, showing clays and shales 6 to 10 



5. Drab inclining to olive argillaceous shales 5' 



6. Bluish-drab limestone, weathering to brownish 3'

8. Shales; olive at top, dark blue at bottom 11" 



9. Bituminous shales, containing at the lower part a bed 

 of indurated pyritiferous shales containing many 

 fossils, viz. : P roductus muricatus^ P. cBquicostatus, 

 MachrocJteihcs, Seleiiofiiya, Orbic/iloidea, Cho?tetes 

 Smitht\ Teniopteris 4' 



10. Bituminous coal 22" 



11. Bluish fire-clay 



There is an exposure on the McGee College -Excello road 

 in the bluft' half a mile west of East Fork, from which the 

 following sequence is easily made out, although thicknesses are 

 indeterminate :
