lation of much glacial debris. An obvious reason for this, per- 
haps, is the temporary position of the ice, as well as the gradual 
slope of the area to the west. 
(/) At several other points throughout the quadrangle, one 
notes in the uplands localizations of drift, more or less kamy in 
texture, that suggest nunatak relationships. The cases are not 
always clear enough to warrant this explanation of the deposits. 
Two localities may be mentioned as typical of these: (i) At Fitts 
Corners is a pronounced kame area, alluded to in the discussion 
of kames (p. 376). Bearing in mind the relationship of this region 
to Fall Creek valley, and noting the topography to the north, 
there is a suggestion of conditions that probably produced, for a 
temporary period, stagnant ice to the south, while there existed 
an ice-free area just northward. The Fitts Corners locality is 
not sufficiently isolated to warrant the name nunatak; neverthe- 
less the probable persistence of ice about the region afforded the 
environment that governs the formation of nunatak drift. (2) 
A further illustration of these areas is the height of land surrounded 
by the 1700-foot contour southeast of Lickville. The irregularity 
of this contour, particularly on the north, marks a drift-collar, 
representing a temporary exposure of this area, while all the 
adjacent region was beneath the ice. 
Parallel Ridges of Drift, In three localities on the sheet I have 
mapped an unusual parallelism of drift ridges. The most pro- 
nounced development was noted east of the highway that extends 
northwest from Owasco Hill; the ridges here are 10 to 40 rods 
in length, 15 to 25 feet high, and from surface appearance contain 
much washed material. 
One-half mile north from Lafayette a highway leads east; near 
the margin of the sheet, and some 80 rods north of this road is 
another series of these ridges; here, however, unmodified drift 
is more abundant than in the former locality, but good sections 
are wanting. In neither case is the characterization as to content 
very accurate. 
A short distance north and west of Benson Corners are several 
ridges, somewhat parallel, but much broader and less sharply 
defined than in the two areas already mentioned. The material 
of these ridges is prevailingly fine, from surface indications. 
Some have a tendency to broaden and flatten towards the north- 
west.
