"Just above the mouth of Circus Creek the following section was exposed: Rest of section above this same as at Rock House. 12 ft, limestone, 57 feet Maranby 3 ft. thin limestone, Lower Wavely seen to be absent. 35 ft. of Black Shale, No nodules. Prof. Miller found one. 4 3/4 ft. heavy limestone, with chert nodules. 8 1/2 ft. thin bedded clayey Madian. 8 1/2 ft not exposed, 80 ft. of clayey limestone, (Overdr - Madian towards middle trip) with fossils, A. This is the layer at top of Rock House Lower Silurian, so it at the base or top of the 20ft. of limestone exposed above Fowler's Landing. Just West of Circus Creek is a strong westward dip of the rocks, there given the oil wells were once situated. The Oil bubbles up, part of the time, and the wells are sunk 700 feet in the northern river bank. 806 3) Views of the westward dipping 4) rocks at the oil wells. Of them 5) is an anticline here the east- ern side of the anticline is not seen here. A little farther west a layer corresponding perhaps to the mass ive Madian at the base of the Madian, and almost immediately overlying beds containing fossils, contains either gun-flints in clay, pebbles of about the same character. The fact that all the pebble, dead about the size suggests that they are nodules! Found 21 feet above river, Nodules 3-3/4 inches in diameter, 2 in. thick. Thin bedded Madian 17 feet thick immediately above, fronted as with chert nodules over this.
