The 3Iarglii of the Cornell Glacier. 145 
enters it. provided the elevation andslope permit; if a piecip- 
itOLis indentation of the land occurs, the ice margin reaches 
further than on the point projecting toward the ice. Coming 
to a nunatak the ice rises against the land on the eastern side, 
then sweeps around it, the two arms meeting at a very much 
lower level at the western base. On the eastern side of the 
partial nunatak mount Hojje the ice surface is about 1060 
feet above the sea, and the nunatak reaches an elevation only 
390 feet higher, or 1450 feet, while on the western or seaward 
face of this nunatak, the mountain rises 1450 feet above sea 
level, and from 1250 to 1300 feet above the ice surface. The 
same feature is seen around mount Schurman. There the ice 
surface is 1750 feet above the sea on the eastern side, andonjy 
1350 feet a mile further west at the western base of the moun- 
tain. Hence this nunatak, whose elevation is 2210 feet, rises 
nearly 1000 feet .'ibove the western ice surface and only 460 
feet above the eastern. About three miles west of this is a 
nunatak Just peeping through the ice stream of the south Cor- 
nell glacier. It is so overridden on the eastern side that it 
cannot be seen from that direction ; but from the west it is 
plainly visible. 
Lund Face. The margin of the ice cap or the glacier in 
contact with the peninsula and the nunatak, is prevailingly 
■characterized b}^ a moderate slope. (Fig. 1, plate VIII). In 
tliis it differs radically from the conditions described by 
Chamberlin and Salisbury for the glaciers north of cape York. 
There a moderate slope of the ice margin was an exception, 
in some cases to be explained by the presence of snowbanks 
at the base; here it is the rule, and is the natural glacier face. 
In all I followed its margin for no less than fifteen miles, and 
in this distance traveled many miles on the actual ice slope. 
Again and again I passed from the ice top to the land. Here 
a vertical slope was the exception. Oftentimes the lower de- 
bris zone of the glacier presented a moderate slope and the 
clear upper ice a precipitous face; but it w^as never necessary 
to go far to find an area in which ascent to the ice surface 
was easy. 
Debris in the Ice. Along this margin I found that Cham- 
berlin and Salisbury have described a distinct separation be- 
tween the debris-free upper ice and debris-filled lower layers
