be said here, however, that after very detailed work in the field 
there appears to be no genetic association between these kames 
and the esker. Hills of washed drift contemporaneous in origin 
with the Mallory ville esker lie to the west; probably a much longer 
esker was developed than may now be deciphered, for the reason 
that the kame type of drift filling the portion of the valley into 
which the esker leads has apparently buried a part of the esker 
1 ridge. 
The striking kame topography south and west of McLean is 
apparently more typical for this type of drift than similar accumu- 
I lations noted elsewhere on the sheet. In the immediate vicinity 
1 an ice-front lake occupied for some time this part of the valley. 
A delta was built into this body of water at McLean; otherwise 
I the broken kame topography is not interrupted till we reach the 
I flood plain deposits some distance east. 
In the wide valley extending northeastward towards Cortland there 
I is near the edge of the sheet, but more typically developed just 
over the boundary in the Cortland quadrangle, another area of 
I kames. Here too, as in the Freeville region, the maximum devel- 
opment is on the south or east wall of the valley. 
Another conspicuous group of drift hills, prevailingly washed 
! in texture, skirts the shores of Lake Como (fig. 14). The kames 
of this region are not distinctly different, save in their slighter 
development, than the sections already described; that many of 
i these drift knolls have been altered is evident from the photograph 
/ shown in figure 15 . Apparently a static body of Water stood here 
' in front of the ice; its greatest areal extent endured pending the 
' cutting down of its outlet through the drift loop just south; lake 
. Como is the remnant of this larger lake. The level of the former 
lake coincided approximately with the tops of many of the drift- 
hills; waves attacked the drift distributing the products; the pro- 
: cess continued as the outlet was lowered; accordingly many of 
these knolls now present a very flat-topped appearance, 
j In this section, too, an esker of sharp development leads south- 
' westward from a slight kame area near the road crossings desig- 
|i nated Como. 
The massed drift which now constitutes the divide between the 
1 headwaters of Fall Creek and Bear Swamp Creek is, in localities, 
I very kamy; but the Water-laid deposits are not sufficiently de- 
veloped to designate the region as a typical kame area.
