 Hall as found at Vanhornesville in the town of Stark.

iron ore but no distinct beds ?

The locality in the town of Canajoharie mentioned by Hall has not 

 been certainly identified. The highest formation occurring within 

 the present limits of the township is the Hudson river. The section 

 may be the one on Canajoharie creek, in Otsego county, or more 

 likely the section north, of Cherry Valley, near Salt Springville, 

 which is approximately at the eastern termination of the Clinton 

 formation. The section is as follows : 



STRATA • FEET 



Coarse sandstone, with much iron ore ? 



Shale ; . ? 



Grayish sandstone, conglomeritic below, darker and laminated 



above , „ , . ? 



Conglomerate (Oneida) ? 



The total thickness is estimated at less than 50 feet. The pres- 

 ence of the Clinton beds can not be ascertained from the exposures 

 at Cherry Valley, and they may have thinned out entirely. At 

 Sharon Springs, 7 miles farther east, the Salina rests directly upon 

 the Hudson River shales, the whole of the Niagaran and Oswegan 

 groups having disappeared.
