Locke. We may call this the North Lansing-Locke valley; it 
has a genetic relation to Salmon Creek valley of the Genoa quad- 
rangle, the first one west. 
Possibly of the same age is the valley extending eastward, with 
a tributary northward, from Montville. In this connection it 
may be suggested that the erosion slope of the area southeast of 
Moravia and east of Montville indicate that the maturity about 
Montville possibly has a genetic association with the work of the 
Locke-North Lansing stream. 
(2) Those of More Recent Cycle. Belonging to a cycle perhaps 
next younger than the one just described are the valleys of Skanea- 
teles Inlet and, in parts at least, that of the Owasco Inlet. Only 
a segment of the Skaneateles Inlet (fig, 5) is included in this sheet, 
in the northeast corner. ^ Glacial erosion has markedly altered 
the cross-section of these valleys as now they are in places walled 
by steep rock slopes; but a study of their cross-sections above 
the U-part of glacial erosion origin shows that they are less mature 
than the drainage lines considered in the preceding section. 
The Owasco valley southward from Moravia to the vicinity of 
Peruville bears several loops of moraine and a few areas of wider 
morainic bands. From the study given the region it is apparent 
that the rock boundaries of the valley narrow about two miles 
north of Groton; there must have been a former divide here for 
there is no stratigraphic cause for the narrowing. On this suppo- 
sition, the drainage which now controls this narrow area indicates 
a more recent period of erosion. 
(3) Those of Inter-glacial Development. The evidence of inter- 
glacial erosion on this sheet is very plain in a few localities, and 
probably more detailed work would discover other examples; 
my study of the sheet has given this matter only incidental atten- 
tion. 
The valley in which Montville lies hangs about 200 feet above 
the flood plain of Owasco Inlet valley; at the southwest corner of 
Main and Walnut streets in Moravia a well 200 feet deep does not 
reach rock, so the height of the hanging is at least 400 feet. The 
mouth of this lateral valley has not just a single channel through 
which its drainage has been let down into the controlling valley; 
but even the contour lines show evidence of two such channels; 
and there is strong evidence of a third apparently buried by the 
massive delta gravels to the north. The road from Moravia to
