GEOLOGIC MAP 



OF THE 



TULLY QUADRANGLE 



The formations represented in this very interesting area extend 

 from near the top of the Siluric continuously upward into the Upper 

 Devonic. The region is one of many fine exposures and though the 

 topography has been in some measure modified by the accumulations 

 of the soil cap, yet here are many typical and classical outcrops of 

 the New York formations. It is moreover within easy reach of Syra- 

 cuse and on this account it is believed the map will be found specially 

 useful to the many students of geology in that city and scattered 

 elsewhere over the neighboring country. 



The units of sedimentation here described may be grouped as 

 follows :
