THE GEOLOGY OF THE SYRACUSE QUADRANGLE 



BY 



THOMAS CRAMER HOPKINS 



INTRODUCTION 



The Syracuse topographic quadrangle, which is here specially 

 under consideration, includes an area one-fourth of a degree square, 

 in latitude 43°-43° 15' N. and longitude y6°-y6° 15' W. Situated 

 near the geographic center of the State of New York, including 

 part of two of the great physiographic regions of the State, and 

 the outcropping edges of many of the stratigraphic units of the 

 paleozoic rock series, it has many features in common with, and 

 hence may be taken as typical of, a rather broad belt extending east 

 and west through the middle of the State. 



The city of Syracuse is on the line of the Erie canal; lies at the 

 intersection of the east-west (New York Central and West Shore) 

 and the north-south (Delaware, Lackawanna and Western) rail- 

 ways, and has besides several branch lines radiating from the city 

 and several suburban electric lines. Central location and excellent 

 transportation facilities make it an important commercial center. 



This quadrangle is located on the border line between the lake 

 plains on the north and the Alleghany plateau on the south, two of 

 the distinctive physiographic regions of the State. It has a varied 

 physiography, which is somewhat intensified by glacial action. Pass- 

 ing across the quadrangle are the outcropping edges of the Siluric 

 rocks with the lower and middle Devonic rocks on the hills near the
