Glaciers of Nagsiidk Peninsula, Greenlavd. — Tarv. 263 
The glaciers seen on the west side of Vaigat strait are fur- 
nished with their supply from the local ice cap, which over- 
spreads the most of Disco island. In the neighborhood of 
Godhaven, the ice cap is easily reached by a' climb of 2,500 
feet, and at tliis point is found to possess an attenuated edge. 
In going from the land to the ice, one passes over patches of 
snow, then, almost imperceptibly, attains the ice cap edge 
without steep ascent. IMiis Is entirely different from the edge 
of the main ice cap which, everywhere that I saw it, presents a 
distinct slope, and oftentimes a precipice toward the land. 
Near the middle of August the surface of this attenuated edge 
was wet and slush-covered, with innumerable streams flowing 
over its surface. Even at a considerable distance from the 
margin, and at an elevation of 3,200 feet similar conditions 
exist. 
Time did not permit extensive exploration of this ice cap, 
but viewed from a high place (about 3,200 feet above sea 
level) it was seen to extend juany miles toward the interior of 
Disco island, with a very irregular surface, evidently con- 
forming to variations in the under topography. Along the 
i^iargin, where we approached the glacier, there was no evi- 
dence of motion, but ever}' appearance of nearly perfect stag- 
nation. Descending from this place, which was a divide, 
toward the valle^^ on either side, evidence of motion was 
found in the crevasses which break the surface of the ice cap. 
Passing down one of these valleys, it is found that the ice 
projects as a valley tongue; and in the case of the larger val- 
ley, as a distinct glacier. On the margin of one of these val- 
leys the ice cap comes to the edge, in some places forming a 
precipice, in other places hanging down over the edge of the 
clitr as a hanging glacier. 
In several of the valleys visited by different parties, evi- 
dence of former greater ice extension was found in the pres- 
ence of moraines, both marginal and terminal, beyond the 
present ice margin. Another notable feature of the glacial 
geology of this island, was the presence of gneissic boulders 
stranded upon the trap rock which forms the cap of this part 
of Disco. These boulders extend all the way up to the edge 
of the ice. Whether they were brought to their places by the 
glacier, at some time when Disco island was more extensively ice
