A CREVASSE AND SNOW BRIDGE 



"In the higher parts of the mountain, as in the Grand Plateau region, the glacier is 

 composed of neve — that is, consolidated snow, not solid ice. It is opaque and stratified and 

 has a dull white luster, instead of being greenish and transparent and of crystalline texture, 

 as in the lower part of the mountain. Lacking in compactness, it breaks easily if subjected 

 to violence, and thus forms crevasses'* (see page 885).
