Glacier is nearly separated into two independent ice tongues. Charpentier and 
Favorite Glaciers have been dismembered since 1906 by recession. Reid, 
Hugh Miller, Wood, and Geikie glaciers in Glacier Bay and Brady Glacier in 
Taylor Bay have changed less rapidly, though they are still receding. 
La Perouse Glacier, west of Mt. Fairweather, and 130 miles southeast of 
Yakutat Bay, changed very little between 1910 and 1911, apparently having 
had in 1910 a brief spasmodic advance of the earthquake avalanche type. 
In contrast with the other ice tongues of Glacier Bay, Rendu and an 
adjacent unnamed glacier have made notable advances. The former retreated 
about 2,000 feet between 1892 and 1907; it then advanced at least 8,350 feet 
and retreated again 600 feet by September, torr. If the rate of the last retreat 
was about the same as the earlier one, the whole of the remarkable advance 
must have taken place in 1907. As Rendu Glacier is only 120 miles southeast 
of Yakutat Bay where nine or more glaciers have advanced since 1899 in 
response to earthquake avalanching, its advance may have been due to the 
same cause, and it will be interesting to see whether any of the other ice tongues 
of Glacier Bay push forward within the next few years. The small cascading 
glacier immediately south of Rendu Glacier has advanced a quarter-mile since 
1907 and was discharging icebergs in 1gIt. 
Southeastern Alaska.—Rainy Hollow Glacier, northwest of Lynn Canal, 
advanced more than 2,000 feet between June and September, 1910, as observed 
by the late Webster Brown. This brief, spasmodic advance in an ice tongue 
only 120 miles east of Yakutat Bay suggests the earthquake avalanche cause 
for activity. Davidson Glacier in Lynn Canal is still inactive; it changed little 
between the visit of G. K. Gilbert in 1899 and that of the National Geographic 
Society party in 1911. Eagle, Herbert, and Mendenhall glaciers, north of 
Juneau, which have recently been mapped in detail by the United States 
Geological Survey, seemed, as seen from a distance in 1911, to have suffered 
little change in recent years. Taku Glacier continued to retreat from 1907 to 
1g11. Norris Glacier, which was advancing and destroying vegetation when 
visited by F. E. and C. W. Wright in 1906, was advancing slightly and over- 
riding shrubs in r911. None of the ice tongues on the Stikine River displayed 
signs of abnormal activity in September, 1911. Popoff Glacier has retreated 
considerably since 1904. 
The Kahiltna, Tokichitna, and Little Tokichitna glaciers, on the 
eastern side of the Alaskan Range, have large trees growing very 
close to their ends, indicating a stationary or advancing phase (S. 
R. Capps). But the glaciers on the western side of the range seem 
to be in retreat (Brooks). About 30 miles east of Cape Yakataga 
the Malaspina Glacier has receded about 10 miles, leaving a good 
harbor (H. Horick).
