YAKUT AT BAY 45 



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
