high. Above this is a slope comprising 5 feet 



of the uppermost Becraft 21 



i New Scotland beds. Shaly limestones forming 

 the middle covered slope of the hill. On the 

 surface are numerous fragments of weathered 

 rock on which the fossils stand out in relief. 

 This is as good a collecting ground of this for- 

 mation as any in the Schoharie region. The 

 upper beds, consisting of a series of argilla- 

 ceous mudrocks with alternating layers of 

 concretionary limestone, are shown better 

 along the rock shelters and at the arch above 

 Sam Clark's house on Dann's hill [fig. 199]. 

 Along the contact line with the Becraft here 

 as well as at Ackers characteristic fossils are 

 found. The upper layers are very calcareous 

 and contain A s p i d o c r i n u s s c u t e 1 1 i -

h Coeymans limestone, massive, dark gray lime- 

 stone, chiefly a lime sandrock. The lower 

 27-1 feet form an overhanging cliff, from which 

 a fine view of the valley below may be ob- 

 tained. The remainder forms a slope, rising 

 about 25 feet in 125 horizontal distance. The 

 upper beds are full of fossils which may be 

 obtained from the outcropping ledges. Thick-
