140 Tne American Geologist. September, 1897 
Xature of the StmUi. Professors Chamberlin and Salisbury 
have recently* described very fully the conditions along the 
margin of numerous valley glaciers, and valle}' glacier tongues 
of the Gi-eenland ice cap, notably those in the Inglefield gulf 
region. The}'^ have also described some of the features along 
the margin of the main ice cap. It seems unnecessary to dupli- 
cate this description by the statement of observations of sim- 
ilar phenomena made upon the smaller glaciers of the Upper 
Nugsuak peninsula region. However, some features seen by 
us differ from those described by these authors, and some of 
the characters described by them were not observed. It 
therefore seems important to state in some detail the condi- 
tions found along the margin of this part of the ice cap. 
Aside from the study of small glaciers and of the evidence 
of former glaciation in the Upper Nugsuak peninsula, consid- 
erable time was spent in the examination of the large glacier 
which terminates in the sea at the head of the deep fjord on 
the south side of this peninsula. The name Cornell glacier 
was given to this hitherto unnamed ice tongue, whose source 
of supply is the great Greenland ice cap. It comes down to 
the sea in a broad valle}^ which at a distance of five miles from 
the front is bounded by mountainous valley walls not less 
than twenty miles apart. As it proceeds toward the sea the 
glacier narrows between the mountainous valley sides, and 
when it ends in the fjord the distance from the north to the 
south margin is seven or eight miles. It has not a continuous 
sea face, but is interrupted by a partial nunatak, whose sea 
front is about 1.8 miles. This nunatak called mount Hope 
divides the glacier into two unequal parts, the northern arm 
being about 1.4 miles long and the southern arm 4.6 miles. f 
There is, therefore, a total sea frontage of about six miles, 
and a curved line parallel to the front of the glacier and one 
or two miles from the sea, is nine or ten miles long. 
The northern margin of this peninsula, for a distance of 
about ten miles, and the contact with the nunatak, mount 
Hope, were studied in some detail, and the surface of the 
front of the ice was also examined. With Messrs. Martin and 
*Jour. Geol. 
■fThese measurements were obtained from a map, for the preparation 
of which I am indebted to Mr. J. A. Bonsteel of the Corneli party.
