association with the conspicuous kame-area at Freeville and 
northward is a question discussed in another place. 
Just north of Freeville where the recently constructed 
highway reaches westward across the valley one notes an incon- 
spicuous accumulation of drift, suggesting a temporary position 
of the ice. This drift does not average over eight feet above the 
general outwash plain, but the alignment of scattered knolls indi- 
cates that the ice halted here briefly at least. The outwash gravels 
of a later ice-halt, and wave work of an ice-front lake which later 
covered the area have rendered less conspicuous this loop which 
had slight initial development. 
C. ’’ At Peruville, an alluvial fan on the west side of the valley 
reaches out almost to the drift which flanks the opposite side of 
the valley. It is noted, too, that the lingering of the ice at this 
point probably commenced slightly south of the present southward 
slope of this alluvial fan, but the melting and feeding factors lacked 
enough of being balanced so that a rather wide, low band of drift 
was developed across the valley. The abundance of washed 
deposits into which this loop blends on the east side, where the fan 
has not partially buried it, is a condition that will be discussed 
elsewhere in connection with the fact that in this part of our 
quadrangle the kame type of drift apparently predominates. 
'‘D.” About half way between Peruville and Groton, the 
drift which all the distance covers the walls of the valley, particu- 
larly the east wall to a considerable depth, narrows down into a 
ridge across the valley. We have to bear in mind constantly 
that through a large part of this Freeville- Moravia valley, moraine 
terraces and other forms of valley drift are so thoroughly developed 
that there is a tendency to mask the accumulation which would 
mark the position maintained for any essential length of time by 
the valley tongue. This condition perhaps accounts for the 
fact that some of these loops are so inconspicuously developed in 
the bottom of the valley that their diagnosis as moraines would 
hardly be permissible without the association of analogous drift 
higher up on the valley walls. 
‘‘E’k Extending across the valley at Groton is another loop 
which has been cut through by a drainage channel probably from 
Its early history. The ice-front drainage maintained for some 
time after the ice had retreated far northward in the valley, an 
outlet to the south. It is thus that the ridge of drift at Groton is
