SCENERY OF SWITZERLAND, 
over 170 metres, and one of the largest of the 
blocks, known as the Pierre de Lisboli, is 15 metres 
in length. Above this moraine the Arve has raised 
the level of the whole valley. 
Chamouni itself is built on, and to a great extent 
of, a former terminal moraine of the Glacier des 
Bois. This is shown by the character of the blocks, 
which are of Granite, very different from the rocks 
of the Brevent. 
Lower down the valley, at Montquart, is another 
moraine, which ends a little below the torrent com- 
ing from the Glacier de Taconnaz. One of the 
blocks belonging to it, known as the Pierre Belle is 
24 metres long, 9 wide, and 12 in height. 
At an earlier period, however, the whole valley 
was filled by the glacier, and all along the face of 
the Mont Blanc range the upper limit of the ice can 
be clearly traced (see Fig. 106, opposite). At this 
epoch the glacier divided, one branch passing down 
the Arve, the other over the Col de Balme, and the 
Tete Noir to the Valley of the Rhone. 
The moraines of the Chamouni district are very 
instructive, because they connect so clearly the 
ancient glaciers of the Ice Age with those of the 
present day. 
Glacial action, moreover, as indicated by the
