 Trenton fossils, with some shaly layers. 12^=25 i 



The interesting thing in this cliff is the occurrence of the two 

 strata, C^ and C*, with the lithologic characters of the Birdseye 

 limestone above the massive limestone of C^ which is apparently 

 the Black river limestone. 



Schoharie creek section 



In a recent paper the writer and Mr Cumings described a section 

 on Bean hill southwest of Minaville where the transition from the 

 Utica slate to the Hudson river formation is clearly shown.^ Since 

 then the writer has discovered a cliff on the Schoharie creek where 

 the transition is beautifully shown and is almost as marked as that 

 between any other two formations in eastern New York. This clift' 

 is on the western side of the creek opposite the house of William 

 Bega, three miles south of Mill Point, about seven and one half 

 miles southwest of Amsterdam and seven and one fourth miles 

 south of Tribeshill station. The section beginning at the level 

 of Schoharie creek near the northern end of the cliff and extending 

 nearly to the top of the hill is as follows: 



Feet 



45 X^ Clear black shale from the water to the base 



of the lowest sandstone stratum in the cliff, 114' by 

 level and 105' by barometer. At the sandstone stra- 

 tum there is a decided lithologic break from the black 

 argillaceous shales below. Utica slate. 114^114 



X2 Grayish sandstones alternating with bluish 

 argillaceous shales to the top of the cliff. Hudson 

 river formation. 195=309 



X^ Mostly covered from the top of the cliff to the 

 highway. 15=324 



X^ Occasional ledges of sandstone show on the side 

 of the hill from the highway nearly to its top. Hud- 

 son river formation. 120=444 



In this cliff the Utica shale is all black and highly argillaceous up 

 to the base of the Hudson river sandstones. The lowest sandstones 

 are thin bedded with some blue shales; but a little higher are thick,
