REPORT OF THE STATE PALEONTOLOGIST I903 205 



of a few cleared fields, is covered with so dense a growth of shrubs 

 and small trees that not only is traveling very difficult, but the rock 

 outcrops are often concealed from view even at the distance of a 

 few feet. This, together with the fact that most of the strata are 

 covered with talus or drift, renders impossible the careful notation 

 of successive beds and their fossil contents which one could wish. 

 Another peculiarity of the region and one which makes the correla- 

 tion of beds still more difficult, is the numerous hogbacks for which 

 the mountain is justly noted. These as already noted are probably 

 due to the greater or less development of certain cleavages over 

 others, rendering the rock more susceptible to the disintegrating 

 influences of the weather along the lines of the more pronounced 

 cleavage. The length of the hogbacks is in the direction of the 

 strike of the beds. At times when the hogback is very short, a well 

 developed cleavage may obscure the strike. 



The following sections are numbered from southwest to northeast 

 along the Bennett road, beginning always on the northwest side of 

 the road.^ 



Section A 



This begins in a small quarry situated about 35 rods northeast of 

 the junction of the Bennett road with the turnpike. This quarry 

 was opened in the lower Oriskany since the sandy nature of the 

 weathered rock renders it available for road material, though not 

 eminently so.
