perienced an important minimum, but the latter history is 
rendered probable by comparison with facts recently de¬ 
veloped about other glaciers of the same mountain face. 
Lituya Bay, fourteen miles northwest of La Perouse 
Glacier, was explored in 1786 by La Perouse, who de¬ 
scribed and mapped the principal glaciers descending to 
it. Klotz has made a comparison of La Perouse’s account 
with the condition found by himself in 1894 (fig. 74), 
and shown that there has been a marked advance of the 
ice in both arms of the bay, the western glacier encroach¬ 
ing three miles on the water of the bay and the eastern 
two and one-half miles. 1 The foot of Brady Glacier, 
twenty-five miles east of the La Perouse, was visited by 
Vancouver in 1794, and from a discussion of his descrip¬ 
tion Klotz concludes that the ice front was then at least 
five miles less advanced than in 1894. Muir in 1880 
found the margin of the Brady against a mature forest 
whose territory it was invading. As the La Perouse lies 
between glaciers of the same range which have experi¬ 
enced a great advance, and as it has recently crowded 
against a forest, the probability is that its history resembles 
that of its neighbors and includes a great forward move¬ 
ment during the last century. 
YAKUTAT BAY 
In the neighborhood of Yakutat Bay a foreland fifteen 
to twenty-five miles broad separates the mountains from 
the open ocean. The bay lies partly in the foreland and 
partly among the mountains. The outer part, to which 
the name Yakutat is more specifically applied, is nearly 
twenty miles broad, but narrows toward the mountains. 
The inner part penetrates the mountain district for ten 
miles in a north-northeast direction, with an average width
