Section F 



A few rods northeast of the last section is a large abandoned 

 quarry in the center of which this section begins. 



Fi The Manlius is here separated into an outer and an inner por- 

 tion by an old quarry floor. It is possible that the outer portion 

 represents a block of the same rock as the inner, that, undermined by 

 the larger stream that formerly flowed through this valley, has fallen 

 to its present position. Such fallen blocks occur ^ of a mile farther 

 to the northeast at what is locally known as the Ramapo Hole. 



Though this explanation is possible it does not seem probable. 

 The strike and dip are the same for both portions of this locality. 

 The fossils also indicate that the rocks are from different horizons. 

 The outer portion (Fi) has a thickness of 13 feet and is much 

 weathered. It has the same lithic character as Ei. No chert band 

 was noticed. The following is a detailed subdivision from the base 

 upward. Lower Manlius. 



Fia Dark blue limestone. Lower Manlius i foot 



Fib Gnarled bed. A concretionary, dark blue limestone, cortir 

 posed almost wholly of nodules varying in diameter from % inch to 

 I inch, which on weathered surfaces are shown to be Stromatoporoid
