Glaciers of Kur/stiak Peuirisitla, Greenland. — Tarr. 265 
peninsula. Its valley walls are steep on the eastern s^ide, and 
only moderately steep on the western side.. There are no dis- 
tinct marginal moraines, although at places accumulations of 
debris extend to the edge and top of the ice. This glacier, 
which discharges the greater part of the surplus of snow in 
the snow fields of this place, is now just able to reach the sea. 
In one place the ice front is bathed by the waters of the fjord ; 
but the greater part of the front, which is about 250 yards in 
extent, is terminated b}^ a small marginal lake, or else b\^ 
moraine upon the land. 
The lake, which is moraine dammed on the seawjird side, 
stands at an elevation of about five feet above high tide. The 
moraine at the terminus is ver}^ bouldery, and in some places 
rests upon an ice foot, forming a thin film. However, in the 
part where the dam of the lake is built.the moraine is situated 
in a place entirely distinct from the glacier itself, as if mark- 
ing the re^;ent retreat of the ice. The front of this valley 
glacier is steep, rising 50 or 60 feet, with an average angle of 
about 50''-60*^, and in its base there are layers of dirt and 
l)Oulders, some of the latter weighing two or three tons. 
^ Dying Glacierfi (Fig.2). Besides these two valley glaciers. and 
one that was not studied, but which exists to the east of these 
two. there are many tin}' accumulations of ice, which in some 
cases are distinct glaciers, in others apparently nothing more 
than snow banks. Among these there are banks of snow, or 
rather of ice compacted from the winter snow, which are not 
in movement, but merely remain from year to year. The 
depth of these may in some cases be 20 or 30 feet. There are 
other banks however, in which one finds lines parallel to the 
outline of the bed, and in the base of which are layers of 
dirt. Among these there are many that are crevassed on the 
surface, showing distinct movement, but no snow fields exist 
to suppl}' the glacier. From an examination of a large num- 
ber of these, I have no hesitation in attlrming, that upon the 
upper Nugsuak peninsula one can find every gradation from 
the snow bank that is motionless, to the distinct valley gla- 
(;ier tongues supplied from snow fields. 
Former Greater Extension. These small glaciers are called 
(Ijliiiy (f/aciers, and in this category may Jtlso be included the 
larger Looped and Nugsuak glaciers described above, although
