A third of a mile North of Petersville, a road turns off Westward up a small creek, and 300 yds Westward forks, one branch going up a steep hill, Northward; A bird half way up the hill, the Sunbury shale is 15 feet thick, and is underlaid shaly sand at me, and about 5 feet below the Sunbury, a 2 inch striation is distinctly visible marked, probably indicating the equivalent of the Berea sand at me. 1/2 mile West of Noah, road turns off towards left, and goes down steep hill. Here Massive sand at me is exposed at top of hill = 85 ft. An interval of 45 ft between between this de and top of Sunbury Sunbury = 14 ft 6 in. Black shale. Barnwell shaly sand at me, with a few ripple marks, at least 8 ft. Interval unknown. Ohio black shale not well exposed. Top of Black shale about 110 feet above spike junction level accords my to estimate only, At Glenn Springs the Silurian lime stone has a sort of light smoky brown color and is, 13 ft 6 in. thick, with black chalky above and beyond clay shale below. A mile + one half from Glenn Spring and 2/3 mile South of Beulah's Spring from base of Ohio shale to base of of Sunbury shale, = about 156 1/2 ft, 13 ft 8 in Silur limestone, Sunbury, in Berea equivalent, a 3 in. layer of sand- at me is beautifully ripple marked. Below this is 10 ft of thin shaly sand at me and the same material occurs above the ripple marked layer. The Berea has lost its characteristic appearance except for the one ripple marked 20. layer. Base 5 ft Sunbury shale exposed, 5 ft covered. 16 ft white clay purple at top, 1 ft layer of freest lime. 10 ft chiefly crowned clay shale and several free lime layers 44 ft practically continuous very soft dreamy freest lime layers. 22 1/2 ft chiefly crowned. chiefly clay shale + thin pure lime. 1 ft strong pure lime 20 ft covered. No evidence of heavy pure lime layers 1ft 3 in. heavy free lime layer of white
