{c) Northeast of Como, a hill, which appears to be an outlier 
of the higher ground still father northeast, reaches an altitude of 
1700 feet. The unusual association of drift on the flanks and on 
the southern end of this hill attracts attention; its western slope 
bears a collar of drift, using a term coined by Tarr,^® while the 
southern extremity of the nunatak bears several knolls of washed 
material. This association is not a definite case of nunatak 
deposit for the reason that the area is so intimately connected with 
the moraine extending northward, already described (p. 386), 
that the typical conditions for a nunatak may be questioned. It 
is clear, however, that the topography exercised an active control 
on the drift in question. 
{d) Just north of the ice-front channel which leads into the 
Skaneateles Inlet valley, is a hill 1720 feet in altitude. The 
topographic relationship here favored the appearance of a nuna- 
tak, and the mapping of the drift about this hill proves that the 
nunatak phase was not of temporary duration. In the Skaneateles 
valley to the eastward a tongue of ice was present sometime 
after the general ice-front had retreated northward. With the 
thinning of the sheet conditions favored a depth of ice to the east 
for some period of time during which the exposed hill maintained 
a nunatak relationship. Here, to a degree not noted elsewhere 
on the quadrangle, the collar moraine is developed. The prow 
or stoss end of the nunatak bears an accumulation of small 
kames, while the leeward slope is covered likewise by knolls of 
washed drift. It should be stated that on all sides of this nunatak, 
save the west, the deposits are sharply demarcated from the slopes 
that are practically drift-free. Towards the west, however, the 
control exercised by the Fall Creek valley has resulted in a con- 
tinuous development of moraine in which it appears that the 
drift of nunatak is not differentiated from the drift of the lateral 
moraine type. 
{e) Southwest of Moravia, Jewetfs hill, which reaches an alti- 
tude of 1448 feet, apparently bore a brief nunatak relationship to 
the ice-sheet. Where the highway, ascending the slope from the 
north, turns directly to the west, a band of thickened drift is 
apparent on the surface, and is proved by well records. The 
other slopes of the hill do not seem to have witnessed the accumu-
