ST. johx.] SECTION IN FALL CEEEK BASIN. 367 



31. Gray, thin-bedded sandstone, 10 to 15 feet exposed; dip 50° to 60°, 

 K 35° E. 



32. Reddish shales, obscure exposure 100 yards across. 



33. Gray, shaly, obliquely laminated, spar-seamed sandstone, forming 

 a marked ledge in first sharp break in the slope, exposed 10 feet; dip 

 65°, K 35° E. This resembles the plant-bearing ledge in the opposite 

 side of the valley, but it is doubtless much higher. 



34. De'&m-covered slope, 25 yards across. 



35. Gray sandstone, 2 feet exposed. 



36. Reddish shales and debris in slope 100 yards across. 



37. Hard, brittle, gray and buff sandstone, prominent ledge, 10 to 15 

 feet exposed; dip 50° to 60° K 30° E. 



38. De'&m-covered slope, 55 yards. 



39. Hard, brittle, fragmentary brown sandstone, 4 feet exposed; dip 

 48°, N. 35° E. 



40. De'&m-covered slope, 30 yards. 



41. Greenish-gray, brittle, fine-grained arenaceous rock, obscure ex- 

 posure. 



42. Red shales, 55 yards. 



43. Thin-bedded, gray sandstone, 4 feet, underlaid by thin layers of 

 fine-grained sandstone ; dip 45°, N. 30° E. 



44. Red shales and debris, 20 yards. 



45. Gray sandstone, like 43. 



46. De'&m-covered slope, 8 yards. 



47. Gray sandstone, like preceding. 



48. Red shales with calcite and debris, 35 yards. 



49. Hard, brittle, rusty- weathered, gray sandstone, 4 feet exposed, as- 

 sociated with gray and dark gray, laminated, fragmentary sandstone, 

 with comminuted vegetable remains; dip 45°, 2sT. 35° E. 



50. De&m-covered slope, 35 yards. 



51. Two ledges of sandstone, separated by'de&m-covered space, 15 feet 

 exposed. The upper ledge is a gray, brown- weathered, shaly sandstone 

 locally ; dip 50°, K 40° E. 



52. Steep slope into depression, with obscure exposures of brown 

 sandstone, 70 yards. 



53. Dark brown, drab-mottled sandstone, 3 feet exposed ; dip 60°, N. 

 40° E. 



54. Drab and red shales, with thin layers of gray sandstone, 45 yards. 



55. Gray, red, and brown-weathered, thin-bedded sandstone, 3 feet 

 exposed ; dip 65°, IS". 35° E. 



5Q. Red and blue shales, 27 yards. 



57. Thin-bedded, hard, blue sandstone. 



58. Red shales, 15 yards. 



59. Gray, thin-bedded sandstone, 2£ feet exposed ; dip 55°, K 40° E. 



60. Drab and chocolate-colored shales, 35 yards. 



61. Gray, spar-seamed, brittle limestone, with obscure traces of fossils, 

 Lamellibranchiates, 2 feet exposed ; dip 40°, 1ST. 40° E. 



62. Drab shales, 25 yards. 



63. Drab-gray, fine-grained, fragmentary limestone, thin bed. 



64. Drab shales, 45 yards. 



65. Dark gray, coarse-textured, and drab, fine-grained lhnestsone, 4 

 feet exposed ; dip 60°, K 40° E. 



G6. Bluish and red shales, including a thin layer of sandstone, 60 

 yards. 



67. Gray sandstone, 4 feet exposed. 



68. Reddish-brown indurated shales, 15 yards.
