is variously attributed to the reddish lichens that grow upon the 
face of the rocks, and to the ‘red snow” (Protococcus nivalis ) 
which in the latter part of the season gives a very notable pinkish 
tinge to the remnant snow banks and the granular surfaces of the 
glaciers. The glaciers take their origin in an undulatory nevé 
surmounting the cliffs. This appears to be continuous with the 
great snow cap of the interior, but from its apparent thinness and 
strong undulation in evident conformity to the rock surface, it 
seems probable that it is, in effect, a local ice cap. It is prob-

Petowick glacier on the other, draw away and discharge the 
surplusage of the adjacent portion of the main ice cap, so that 
it does not push forward over the edge of the Crimson Cliffs. 
At any rate, the glaciers that creep down the face of the Crimson 
Cliffs are all small and give no hint of relationship to anything 
beyond the limited though rather considerable snow fields on the 
summits immediately above them. These little glaciers descend 
steeply, winding through their narrow valleys in full conformity 
to topographic demands. The most of them do not fully reach 
the sea level, but terminate at varying heights above it. A few 
actually protrude into the water, and have vertical frontal cliffs. 
Terminal and occasional medial moraines are present. There 
appears here an interesting phenomenon which was frequently
