" extends from the divide at the Tully lakes northward for two 

 miles . . . The moraine is very gravelly and the hills are really 

 kames. . . . The small northern lakes seem to occupy kettles in 

 the moraine filling. The outlet channel may be regarded as begin- 

 ning below the lower lakes, Crooked lake and Tully (Big) lake, 

 which have an elevation of 1193 and 1189 feet. These are shallow 

 and probably lie in depressions due to ice blocks. The Tioughnioga 

 valley, which heads at this point, will be discussed, with its heavy 

 detrital deposits, at some future time." In another paper ^ the same 

 author states that, " In the Onondaga valley the highest water was 

 the Cardiff lake which had its outlet south through the Tully lakes," 

 but it does not appear that the promise of publication on the features 

 of the Tioughnioga valley has been yet redeemed. The most recent 

 paper relating to the region is New York .State Museum Bulletin 171, 

 by T. C. Hopkins, entitled " The Geology of the Syracuse Quad- 

 rangle " in which there is a brief discussion of the channels and ter- 

 races of the Onondaga valley (p. 41-42) but no specific description 

 of the glacial history of its south end is included. Inasmuch as this 

 south end lies in the Tully quadrangle, its description would, indeed, 

 not have been warranted under the title. 



For a detailed record of the basic geology of the Tully quadrangle 

 with a map showing the differentiation of the rock floor on which 

 rest the superficial deposits here discussed, reference is made to

The Particular Phenomena of the Tully Glacial Series 



Drumlins. The flow of the last advance of the glaciers, and pre- 

 sumably of the earlier advances as well, was turned by the Adiron- 

 dack uplands from a direct southerly course into the Ontario basin 

 and from thence the ice deployed southeast across the level lowland 

 of the lake plains to the face of the Appalachian plateau escarpment 

 described on preceding pages. The parallel orientation of the drum- 

 lin hills so markedly apparent in the photograph of the relief model 

 gives a clear index of the line of motion of the mass, at least in its 

 declining phases, and the fact that the ordering of the drumlins is in 

 exact alignment with the valley channels opening southward into 

 the plateau uplands is indicative that such was also the direction of 

 flow during the major occupation.
