YALE GLACIER 



amount, although greater than in the case of La Perouse 

 and Columbia glaciers. The Crescent is comparatively 

 narrow, and approaches the sea with a higher grade. A 

 curve in its trough conceals its upper course. 



The Yale drains a larger area and receives a number of 

 tributaries. The front of the cliff is wide, but of moderate 

 height, and a blackening, west of the middle, by englacial 

 drift suggests that a rock knob may lie near the surface, 

 ready to develop into a nunatak or island if the glacier 

 shall diminish. The trough in which it lies is forested 

 along the water edge on both sides for the greater part of 

 the distance 

 from the main 

 fiord to the 

 glacier, but 

 barren in the 

 immediate 

 vicinity of 

 the glacier. 

 There are 

 straggling 

 trees high on 

 the valley 

 wall at 

 end of 

 glacier, but 



they do not come down close to the ice. An excellent 

 photograph of the glacier is reproduced at page 128 in 

 volume i. It is enlarged from negative 113, U. S. Biolog- 

 ical Survey. A nearer view of the eastern part of the 

 front (fig. 43), although lacking detail at the critical 

 point, may serve a purpose for comparison when the gla- 

 cier shall be revisited. It shows a small tributary, cas- 

 cading from a hanging valley near the end of the main 

 glacier.
