A relationship of major and minor valleys, similar to that just 
described, exists also at this point. The direction, however, of 
the tributary valley is more normal to the major stream, and there- 
fore has not offered as favorable a topographical position for the 
development of a loop. 
Lake Como, an unusually large kettle lake, is bordered on the 
north and east (figs. 14, 15) by leveled drift hills in which gravel 
largely predominates. The kame-like aspect of the drift to the 
north and east of the lake is suggestive of the particular outline 
that the ice-front, as it lingered in this region, presented. 
’’ For something more than two miles north of the vil- 
lage of Como the drift of Fall Creek valley does not indicate any 
long stationary halts of the ice, but near the present divide of the 
Fall Creek-Bear swamp drainage areas we have a well developed 
mass of drift which analyses itself into two or possibly three posi- 
tions of the ice. The drift, however, is so irregularly dissected 
in part probably because of the drainage which came through this 
section as the ice was in the neighborhood north, and in part too 
because of the lateral valley slopes, that one does not feel safe in a 
final statement as to the several distinct positions which the front 
of the valley tongue may have maintained. The southern line 
of the next quadrangle north cuts a valley loop, the major portion 
of which lies within the Skaneateles quadrangle. 
(3) Other Loops Principally in Tributary Valleys. ‘‘O.’’ 
The Skaneateles Inlet valley presents a mass of drift that cannot 
be differentiated into loops, if they exist, without a more complete 
study of the region to the east which lies without the quadrangle. 
Fig. 13 gives a general idea of the irregular surface of the drift 
which buries this valley. 
‘‘P.’’ At Dresserville there is a strong suggestion of an ice- 
halt. The valley here is evidently deeply buried with drift, as is 
shown by well sections, some distance away from its axis. But 
in the main, this valley, especially north from Dresserville towards 
Morse Mill, presents such a heterogeneous surface that one does 
not feel safe in interpreting the drift from a standpoint of valley 
loops. There are, however, some very marked suggestions, par- 
ticularly on the eastern wall, of aligned deposits of drift that inti- 
mate the loop type. 
“Q.’’ At Wilson’s Corners about a mile north of Montville 
the vallev is completely barricaded by a very distinct loop. The
