GLACIAL STUDIES IN GREENLAND. 837 
northwestern limb of Bowdoin Bay, known as Krakokta Cove. 
In the portion opposite the Sentinel nunatak the ice does not 
push against the promontory, although it would do so if its 
border described a natural curve. The ice holds aloof, so to 
speak, and leaves space for a drainage stream and a terminal 
moraine. This is perhaps due to heat reflected from the 
nunatak. 
This relationship may be seen in Fig. 55, as well as the 
much more interesting relationship of the glacier to its moraine. 
In the foreground, it will be observed that a fine terminal 
moraine has been formed outside the present border of the ice. 
In the center of the figure, however, it will be noted that the 
ice has advanced over this and has taken on a peculiar rounded 
border, much as though it were rolling forward over the moraine, 
while the bottom of the ice was being held back by friction. 
And this is not altogether an illusion, although the process 
scarcely amounts to rolling. 
Quite in contrast with this aggressive disposition and this 
convex front is the concave front and retiring disposition shown 
only a few score rods back along the same border, where it falls 
behind the moraine shown in the foreground of Fig. 55. If we 
climb over this moraine and descend to the ice, we have the 
view shown in Fig. 56. It will be observed that the ice here 
has neither the tumid, advancing brow which it takes on a little 
farther east, nor the vertical wall which is common to the region, 
but a sloping face with a concave tendency. At the same time, 
the stratification assumes almost the regularity and symmetry of 
a musical staff. The amount of débris borne between the ice 
layers, as will be seen, is not very large, and seems to ill accord 
with the massiveness and coarseness of the moraine. It is to be 
noted, however, that the ice extends beneath the moraine, and that 
the latter may, therefore, owe its material largely to ice layers now 
concealed. The amount of buried ice could not be determined, 
but apparently its mass was large and constituted a considerable 
factor in the make-up of the moraine. On the melting of this 
the irregularities of the moraine will doubtless be accentuated. 
Along this sloping border of the ice a suggestive view
