VARIATIONS OF GLACIERS 669 
appearance of the glacier indicates that it has been stationary during 
recent years." 
The Arapahoe Glacier, Colorado, does not seem to have changed 
since 1907, though the winter of 1907-8 was very dry (Henderson). 
The Hallett Glacier has receded slightly (W7lls). 
Professor W. D. Lyman reports that there are large glaciers along 
the Olympic Mountains in Washington. In particular, the Ho 
Glacier, on Mt. Olympus, is almost comparable with the glaciers of 
Mt. Rainier. 
Mr. Fremont Morse, of the United States Coast and Geodetic 
Survey, has kindly sent the following account of the Alsek Glacier, 
and others near it, at the southeast end of the Brabazon range and 
northwest of the Fairweather group: 
The Alsek Glacier is divided at the discharging face by a nunatak, and the 
lower portion discharges into a deep lake in which the largest bergs float around 
freely. The face showed no perceptible change in location between 1906 and 
1908, but this portion of the glacier was considerably more active than it was in 
1906, according to the report of my assistant, Mr. L. Netland, who was up the 
river both seasons. The upper portion of the glacier, above the nunatak, is 
apparently dying. The ice in it is all dirty, and but few bergs were detached from 
the face while we were in the vicinity. ‘The face has retreated since 1906, and 
at the low stage of the river in September there was a gravel bar exposed in front 
of the ice face. 
The next great glacier up the river is on the right bank in the next bend of the 
river. It is directly connected with the great ice-reservoir from which the nunatak 
and Hidden glaciers discharge into Russel Fiord, and from which the Yakutat 
Glacier flows toward the ocean. This glacier seems to be retreating. Its front 
is now about two and a half miles from the river bank. 
At the second canyon of the Alsek the glacier which forms the left bank of the 
canyon seemed to be advancing slightly on its east side. There the ice was crush- 
ing the alder bushes on the lateral moraine in one place that came under my notice. 
I cannot say whether the front of the glacier had advanced since 1906, but Mr. 
R. D. Ritchie, assistant to the Canadian representative who was with my party, 
and who was up the river in 1906, said the glacier was much more active than at 
the time of his former visit. 
I judged from the appearance of the numerous small glaciers in the canyons 
that the general movement of the ice in the region adjacent to the Alsek was one of 
retreat.
