GLACIAL STUDIES IN GREENLAND. S41 
creeps out upon it, but pushes entirely across it and down its 
outer slope until the glacier’s foot rests essentially on the flat 
ground at the head of the bay. It has apparently made a 
descent on the outer slope of the moraine of more than 200 feet. 
Some allowance, of course, is to be made for the burial of the 
base of the glacier, and for illusions that may spring from 
Ene mestiney Otte moraine oni the edgevot the ice. )) Phere is) no 
room, however, to doubt that the moraine is really very massive, 
for the glacier is much crevassed where it crosses it, as shown 
partially in Fig. 58, and again in Fig. 59. Not only is it cre- 
vassed on the border, but the course of the overridden moraine 
may be traced along the surface of the glacier by the line of cre- 
vassing to which it gives rise. This crevassing was sufficiently 
pronounced to occasion some difficulty in crossing the upper 
surface of the glacier at the most remote point to which the rup- 
tured tract could be traced, z. e. at the point where it merged 
into the crevassed field occasioned by the descent of the glacier 
from the upland, previously noted. 
Fig. 58 shows the border of the Krakokta glacier at the 
point where the terminal moraine is disappearing beneathit. The 
ice wall on the right, which here resumes the vertical habit of the 
region, is notable for the distinctness and regularity of its strati- 
fication. It will also be noticed that here, as elsewhere, the beds 
at the base of the ice are inclined upwards. At the foot of the 
picture we catch a glimpse of the vanishing border of the moraine. 
In the center the crevassed border of the ice is seen very imper- 
fectly —because of the oblique line of vision—as it descends 
the outer slope of the moraine. The border is riven into 
pinnacled masses and these are leaning and even toppling over 
as they descend the slope. The purity of the upper portion of 
the ice is in striking contrast to the dirtiness of the débris-set 
base. At the left and below there is a delta plain formed by 
wash brought from under the glacier at the foot of the cataract 
previously described. 
If we now descend to this delta plain and ascend the 
heights opposite and reverse our line of vision, the general aspect 
of the upper surface of the glacier where it is creeping over the
