DAVIDSON GLACIER 
13 
There may be much unmelted ice beneath the visible 
gravel, but the lowland certainly contains a great body of 
gravel which, if glacier and ocean were withdrawn, would 
appear as a great curved ridge of water-laid moraine stuff. 
Glacier and moraine together encroach nearly two miles 
on the water of the fiord— a branch of Lynn Canal called 
Chilkat Inlet — reducing its width to about one mile. 
FIG. 3. DAVIDSON GLACIER. 
View of terminal fan from the high peak at the right in fig. 2. Shows the barren and 
forested zones of the fringing plain. The glacier is partly concealed by a rock of the fore¬ 
ground. From a photograph by J. J. McArthur, 1894. See page 6. 
The depth of the moraine, or moraine-delta, where it 
occupies the middle of the fiord is more than 500 feet. 
The profile of the ice fan, as shown by photographs, has 
a slope of one foot in ten (see fig. 4). The gravel low¬ 
land is much flatter, but the submerged face of the deposit 
descends to the bottom of the fiord with a general rate of 
one foot in three. 
We made no landing here, and our facts are derived 
chiefly from Russell, who visited the foot of the glacier in 
1889; from the Coast Survey chart, based on surveys in 
1890-94; and from photographs made by the Canadian
