SERPENTINE GLACIER

favorable to luxuriant growth. Translating these facts into 
terms of glacial history, it seems probable that the Barry 
had been, at some time within the century, somewhat 
larger than when we saw it, but that it had not for a series 
of centuries exceeded the limit marked out by the neigh¬ 
boring forest. If any change had occurred within the 
last year or two it was of diminution. 
The opposite wall of the fiord is forested down to the 
water’s edge, and it is thus shown that no recent advance 
of the glacier has carried it completely across the channel. 
Next west of the Barry is Serpentine Glacier, coming 
down to the fiord from the north. It is a broad stream, 
of low grade, fed 
by four or five 
tributaries de¬ 
scending steeply 
from amphithea¬ 
ters in the encir¬ 
cling mountains. 
Though it reaches 
the sea, it yields 
few bergs, but is 
building a mo¬ 
raine barrier 
along most of its FIG ‘ 5 °‘ serpentine glacier.

front. Its medial 
and lateral moraines are conspicuous, especially the north¬ 
ern lateral. Like the Turner and Reid, it seems to rest 
on a valley floor considerably above the floor of the 
fiord to which it is tributary. Its most westerly branch 
(fig. 50) heads in a high valley not fully commanded from 
the fiord and falls to the main glacier in two fine cascades. 
At the level of the upper cascade, 3,000 to 4,000 feet above 
tide, are three hanging glaciers, perched in alcoves of the 
valley wall where it curves to join the wall of the fiord.
