﻿73 Howe's Cave 23 



dence in the lowest beds of the quarry, just north of the railway 

 track. 



Schoharie. — Only about 5 miles distant from Howe's Cave are 

 the well-known quarries of Schoharie. Clinton S. Becker's 

 quarry in the eastern edge of the town is a good sample of these 

 fine exposures. 



Section of Becker's (Ty., Schoharie, N. Y. 



Ft. Thick 



1. Helderbergian with Gypidula, At. reticularis, and many 

 Crinoid stems and other fossil remains I5-0+ 



2. Transition with Dalmanites, and Stropheodonta et at 5.2 



3. Blue limestone in rather thin layers ( 2-6 inch ) showing ir- 

 regular bedding planes, and often separated from the next high- 

 er la3'ers by a 3 inch shaly layer that is easily weathered out. 



The surfaces of thin layers are literally covered with Sp. vanux- 

 emi, Tentaculites gyracantheus, Leperditia and Stropheodonta 

 varistriata . Gasteropods and Orthoceras are not rare. The 

 edges of the thicker layers, upon weathering show the brownish, 

 rough appearance, with Stroph. varistriata cross-sections men- 

 tioned in our discussion of the Union Springs and Manlius sec- 

 tions 8.5 



4. Fairly solid layers, with many Leperditia 2.8 



5. Solid blue bed ; fossil lamellibranchs 2.0 



6. Black, shaly limestone, with Sp. vanuxemi in great abund- 

 ance 4.5 



7. Solid blue bed 2.6 



8. Rather thin-bedded layers, with occasional Stromatoporcc 

 about 1 ft. from top of bed ; Tentaculites very abundant on sur- 

 face of some layers 8.4 



9. Heavy blue beds, with Leperditia, Sp. vanuxemi and 

 Tentaculites 4.7 



10. Heavy blue bed, fossils as in No. 9 2.6 



11. Floor of quarry of shaly, calcareous, gray, mud-cracked, 

 thin layers. 



The transition from solid to somewhat alternating wavy layers 

 is well shown in the accompanying plate, from a photograph by 

 Mr. J. L. Rich of our company. The heavy basal beds, 9 and 10 

 of our section, are evident. The uppermost central portion 

 shows Coeymans layers ; but as the section was not made at the 

 particular place photographed, it is difficult to locate the desribed 

 beds in the photograph accurately.
