GLACIAL STUDIES IN GREENLAND. 843 
moraine and down its outer slope may be viewed to advantage, 
as fairly well illustrated in Fig. 59. 
We are here looking in a direction opposite to that from 
which we have approached in the preceding description. The 
right hand portion of the glacier in the middle foreground is the 
part which has pushed over the moraine, and crept down to the 
delta plain which occupies the low land at the right of the figure 
between the glacier and Krakokta Cove. The ice-strewn surface 
of the latter appears in the center of the picture. Near the 
middle of the picture the jagged edge of the glacier indicates the 
crevassing produced by its passage over the moraine. The line 
of crevassing across the upper surface of the glacier is not 
brought out in the picture. Beyond this jagged edge the moraine 
may be seen imperfectly as a dark mass. The promontory in the 
background is the Sentinel nunatak. The Bowdoin glacier lies 
at the right of this, debouching into the head of Bowdoin Bay. 
In the distance, at the right, are seen dimly two of the lobes of 
the main ice-cap. The latter covers the heights between these, 
but is not differentiated from the sky, in the photograph. 
From the relations of the Krakokta glacier to its moraines 
it is obvious that, in recent years, it has been stationary or 
retreating at some points and advancing at others. The gains 
and loses very nearly balance each other. From the massiveness 
of the moraines and the manifest slowness of the glacial action 
it is probably safe to infer that the border has occupied nearly 
its present lines for a considerable period.
