gorge cut in the north wall of the buried valley. The upper 
rock surface represents the approximate bottom of the hang- 
ing valley. Figure 3 is a view from near the same point as 
figure 2, but looking in the opposite direction (westward). The 
broad flat (B, Fig. 7), now transformed to a lake by a dam 
where the steam is rising, is the site of the buried gorge which 
Fall creek crosses diagonally. The dam is in a post-Glacial 
gorge where Fall creek once more enters the rock, this time on 
the southwestern wall of the buried gorge. The site of this 
dam (now enlarged) is seen in figure 4, which also shows 
the post-Glacial gorge and waterfall (C, Fig. 7). These three 
pictures illustrate the contrast in the valley form of the post- 
Glacial and the buried gorge sections. 
From C to the delta (Fig. 7), the stream tumbles through 
a gorge, descending 300 feet or more in less than a mile. Figure 
5 looks from the west into Lower Fall creek gorge, the fall 
being at the point E in figure 7. Cornell University stands 
approximately on the 800 foot contour line, near the point 
where the slope of the valley wall changes (Figure 16). It 
is on the edge of a hanging valley, occupied on the right by

Fall creek, on the left by Cascadilla creek (Fig. 8), which 
comes down the hill slope to the right of the right hand tower 
(Fig. 5). Between these two creeks, as well as north and 
.south of them, practically continuous rock is traced, eliminat- 
ing the possibility of a buried valley, other than a gorge. Fig- 
ure 6, taken from the bridge back of the fall (Fig. 5; at 
D Fig. 7), and looking westward across the delta toward the 
point where figure 5 was taken, gives an idea of the slope below 
the hanging valley, down which Fall creek descends. 
Were this the only instance of its kind, it might be as- 
sumed that Fall creek valley is not a real hanging valley but 
that, as professor Fairchild suggests,* it may represent drain-
