chains, and the geological structure of the country. 
There are many cases of anticlinal valleys; that is to 
say, of valleys (see ante, p. 70) which run along what 
was at one time the summit of an arch, as, for in- 
stance, the Maderanerthal (Fig. 24) and the Val de 
la Tiniere (Fig. 98). 
In other cases a piece is cut off from the rest 
of the massif to which it belongs, as, for instance, 
the Frusthorn from the Albula massif by the Valser- 
thal. 
I here are others where a mountain, or range of 
mountains, occupies the line of a former valley. This 
is the case for instance with the mountain ridge 
which runs between the Rhine and the upper Linth 
from the Kistenpass at the head of the Limmerbach 
to the south of the Limmern Glacier, by the Biferten- 
stock to Piz Urlaun and Stock Pintga or the Stock- 
er 011 ’* Phis range of mountains occupies the site of 
an original valley, but no doubt from the greater 
hardness of the rock and its position it has offered 
a more successful resistance to attack; while the 
oiiginal mountains have been washed away. 
In this way some at anyrate of the transverse 
langes have, as it were, been carved out. Thus the 
Safienthal — the valley of the Glenner which falls into
