DAVIDSON GLACIER 



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 gravel which, if glacier and ocean were withdrawn, would 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
