covered, and brought from within the island itself, or whether 
they were brought to their present places by a more general 
ice sheet, reaching out from the mainland, was not deter- 
mined. No doubt a study of the bed rock on the mainland, 
and a comparison with the transported boulders will decide this 
point. From what I saw farther north, I am inclined to be- 
lieve the latter the more probable explanation. 
The L()o/te(J Glacier of the Upper Nniisuak Peninsula. In the 
Upper Nugsnak there is no yeaeral ice covering atpres(int;* 
but there are numerous glaciers of various sizes, resembling 
in many respects those that were seen further south. The 
largest valley glaciers of this peninsula were located on the 
northern or sheltered side, and in the inland valleys, at the 
base of a high mountain which reached from 2.500 to 3,000 
feet above the sea. In such an interior valley, near the middle 
of the peninsula, a glacier descends toward the interior from 
the extensive snow fields, which also supply another glacier, 
described later as the Nugsuak glacier. The tongue which de- 
scends toward the interior was call the Looped glacier, because 
of the outline of its margin. It is a hanging glacier, descend- 
ing from the edge of a low part of the valley wall. In some' 
i;)(»rtions the looped edge is attenuated, and ends in melting- 
ice, with no sign of movement, and no distinct moraine. In 
the main and northern loop, the ice assumes the condition of 
a true vallev glacier, whose surface is roughened b}' crevasses 
and by melting. Its terminus is a precipice, and its base is 
lined by morainal debris. In the lower layers of this tongue 
there are distinct dirt bands and man}'- boulders. The glacier 
])resents no specially remarkal)le features, and is merely men- 
tioned to illustrate one of the conditions of glaciation at 
present existing on the Nugsuak peninsula. 
The y iii/tiiia/i- Glacier (Fig. 1). From the same snow field 
as that which furnished the ice for the Looped glacier, there de- 
scends, from an elevation of probably not less than 2,000 feet, 
a distinct tongue of ice. the most notable valley glacier on the 
*This peninsula is in latitude 74 deg. 10-15 min., and was the place se- 
lected for study by the Cornell party which accompanied Lieut. Peary 
in the Greenland Expedition in 1896. Besides myself the members of 
the party were Prof. A. C. Gill, and Messrs. J. O. Martin, T. L. Watson, 
E. M. Kindle and J. A. Bonsteel. To all of these mc-n I am indebted 
for valuable aid in my studies.
