»Ames horizon 6 ft. 91 ft. 



Raymond: Sections in the Conemaugh Series. 167 



limestone are exposed, but the bank is so overgrown with vegetation 

 that it is not now possible to make satisfactory measurements. The 

 Morgantown here is a cross-bedded sand)' shale, and not a compact 

 sandstone. At Beatty the Pittsburgh coal goes below the level of the 

 railroad track. 



The section compiled from these two large cuts is as follows, in 

 descending order : 



34. Structureless clay, grading into residual soil at the top. 



33. Thin-bedded clay shale, very black at the base, green and some- 

 what sandy above. Birmingham horizon. 49 ft 49 ft. 



32. Structureless red clay. 12 ft. 6 in 61 ft. 6 in. 



31. Thin-bedded fissile shale, with small red nodules. 23 ft. 6 in... 85 ft. 



30. Shale and limestone with abundant marine 



fossils. 3 ft 



Black shale with a few marine fossils. 3 ft. 



29. Coal.. Harlem horizon. 14 in 92 ft. 2 in. 



28. Red structureless clay, weathering gray and yellow. 14 ft 106 ft. 2 in. 



27. Thin-bedded red shale. 7 ft. 6 in 113 ft. 8 in. 



26. Structureless clay, weathering red, gray, and yellow. Contains 



many nodules of limestone. 14 ft. 8 in 128 ft. 4 in. 



25. Thin-bedded clay-shale. 14 ft. 6 in 142 ft. loin. 



24. Red structureless clay. 9ft 151ft. 10 in. 



23. Heavy-bedded sandstone. A layer of coal from I to 4 inches in 

 thickness occurs near the base of this sandstone. It can be 

 traced only about 25 feet, and is bent and contorted. Cow 

 Run horizon. 45 ft 196 ft. lo in. 



22. Thin-bedded black shale. 5 ft 201 ft. 10 in. 



21. Limestone with marine fossils. 6 in. Pine Creek horizon 202 ft. 4 in. 



The continuation of this section is taken from the big cutting east 

 of Donohoe station. The dip here is to the northwest. 



21. Shale with marine fossils. 6 in. Pine Creek horizon. 



20. Thin-bedded yellow sandy shale. 10 ft 212 ft. 4 in. 



19. Yellow shaly sandstone which breaks down readily on exposure 



to the weather. 25 ft 237 ft. 4 in. 



18. Light gray, very compact sandstone. At the base and 10 feet 

 above the base there are irregular layers of conglomerate which 

 is made up mostly of small, well-rounded quartz pebbles. 42 ft. 279 ft. 4 in. 

 18, 19, 20 are the Buffalo horizon. 



17. Thin-bedded dark gray and black shales with plant remains and 



lamellibranchs. 12 ft. 6 in 291ft. loin 



16. Thin-bedded black shales with marine fossils ~ 



and small red nodules. 10 ft 



Two layers of compact limestone with ma- 

 rine fossils. 3ft 



Brush Creek hori- 

 zon. 13 ft 304 ft. 10 in.
