C® Thin bedded Trenton limestone containing 
Trenton fossils, with some shaly layers. 124251 
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 Ct 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 cliff 
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: 5 
‘Feet 
45X1 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 + i 
argillaceous shales below. Utica slate. II4—114 
_ X? Grayish sandstones alternating with bluish e 
argillaceous shales to the top of the cliff. Hudson 
river formation. 195309

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. 120444 
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,
