ADVANCE AND RETREAT OF CANADIAN GLACIERS 729 



south, and when the morning sun finally strikes it, the first portion 

 to be touched is the northern side. This glacier also has little fall, 

 and its front is steep. Its valley is terraced and shows evidence of 

 occupation by a great glacier in the. past, and Moraine Lake is held 

 up by a debris dam; but there are no modern terminal moraines 

 other than the one now being - - ,.:,:.^f:;-M 

 formed. This glacier, there- 

 fore, is larger at present than 

 at any very recent time. It 

 is a significant fact that this 

 glacier, which is advancing, 

 should be much more deeply 

 covered with debris than other - 

 similar ones which are retreat- 

 ing slightly. 



Glacier in Consolation Val- 

 ley. — Consolation Valley is the 

 largest tributary of the valley 

 of the Ten Peaks. It is simi- 

 lar to the two preceding val- 

 leys in the presence of lakes 

 in the lower part of its course, 

 and of a debris-covered glacier 

 at its head. This glacier seems 

 to be little visited, and was 

 omitted entirely from the Canadian survey map (Lake Louise sheet, 

 1902). 



The trend of the valley is northward; consequently the glacier is 

 not shaded in the early morning. As a result, it faces directly down 

 its valley. At its upper (southern) end this glacier begins in two 

 alluvial cones which meet from opposite sides of the valley. It is 

 fed mainly from its southwestern end and side, from cliff glaciers on 

 Mount Fay (Fig. 4). CHffs bound its southwestern side, and from 

 these cliffs several alluvial cones extend, in some cases reaching the 

 ice and loading it with material. The consequence is that the glacier 

 is streaked with ridges of material of various kinds and colors, accord- 

 ing to the source. These ridges bear a general resemblance to
