south is clear from the dip of the strata (Fig. 121, 
ante, p. 144). 
Moreover, some fragments of the Secondary strata 
still remain preserved in the deepest folds. At both 
ends of the ellipse Jurassic strata run up for some 
distance, as for instance, on the west, the Jurassic 
belt which quits the Valais at Raron and runs north- 
east by St. German, Leiggern, and the Kriiliggrat 
towards the Hohe Egg. 
To the east and west, however, these are cut off 
by denudation. Along the northern border of the 
gneiss, a series of Jurassic rocks extends at intervals 
from the Ferden Rothhorn by the Tellispitzen, on 
the flanks of the Breithorn, by the Ebnefluh, the 
Jungfrau, and Monch. 
More in the centre of the region another line 
commences with the Blauberg,* (so called from the 
bluish Jurassic rock, which makes a striking contrast 
with the surrounding Crystalline region), and is also 
exposed at Farningen in the Meienthal, at Rothbergli, 
and at Staldi in the Intschithal.** Lastly, on the 
south comes the Jurassic fold of the Upper Valais. 
Another evidence is that the northern transverse 
valleys, instead of tapering to the ridge, run boldly 
* On some maps it is marked as the Greissenhorn.
