the Onondaga over considerable areas in central New York, the 
Oriskany sandstone is present in many districts. The irregular 
distribution and great variability in thickness of the Oriskany 
seem to indicate that the widely scattered patches of the formation 
represent the remnants of the formation which have been left by 
the cycle of subaerial erosion which preceded Onondaga deposition. 
These scattered patches of the Oriskany vary in central New York 
from 1 ft. or less to 18 or 20 ft.’ in thickness. The latter thickness

has been reported for the Oriskany on the east side of Skaneateles 
Lake by Schneider. The contact of the Onondaga and the Oriskany 
is well exposed in the vicinity of Jamesville, N.Y. In the cliffs 
near the lake, one-half mile northeast of town, the Oriskany is 
represented by 30 inches of hard, dark-gray, quartzitic sandstone 
containing Spirifer arenosus and other Oriskany fossils. The
