Zurichberg. On the right are two ridges. The nearer 
and lower one is the lateral moraine of the glacier 
during the last Ice Age; the upper ridge is the 
Albis, 1 500 feet in height, consisting of Mollasse and 
corresponding to the Zurichberg. The very summit 
of the Albis is also capped by glacial deposits, and 
the glacier extended at one time as far as Waldshut. 
The hotel on the summit of the Uetliberg stands 
partly on Mollasse, partly on the Moraine. 
After a long period the climate improved, the 
glacier retreated, and the melting ice caused torrents 
which cut into and redistributed much of the material 
brought down by the old glacier, forming great fluvio- 
glacial deposits, more or less cemented together, and 
(see mite, p. 57) known as “Deckenschotter.” Im- 
mediately under the restaurant at the summit of the 
Uetliberg is a considerable thickness of this deposit, 
forming perpendicular cliffs, under which are remains 
of moraine. The “Deckenschotter” being pervious, 
and the moraine impervious, to water, springs occur 
at the junction of the two. 
The glacier during the Second Ice Age also ex- 
tended to Waldshut. It does not appear, however, 
to have stood very long at its extreme limit. The 
terminal moraine is unknown. To this period, how- 
ever, belong the side moraines at Zugerberg, Hohe
