glacier. A third group encircles the lower end of 
the Lake of Baldegger. 
In the valley of the Reuss is perhaps the finest 
group of all, consisting of five ridges forming an 
amphitheatre round the little town of Mellingen. The 
Heiterberg, between the Reuss and the Limmat, is 
also encircled by one, which reaches a height of no 
less than 100 metres. 
In the valley of the Limmat there is a fine 
terminal moraine at Killwangen, another below 
Schlieren, a third at Zurich, and a fourth forms the 
bank which crosses the Lake at Rapperschwyl. These 
terminal moraines are connected by lateral moraines 
running along the sides of the hills. They do not 
mark the greatest extension of the glaciers, but in- 
dicate places where the glaciers made a stand during 
their final retreat. 
The moraines on the south of the Alps are even 
more astonishing. Probably from the steeper slope, 
and more rapid melting under a southern sun, .the 
ends of the glaciers do not appear to have moved 
so frequently. Hence the terminal moraines are 
more concentrated, grander, and higher. They form 
immense amphitheatres terminating in ridges several 
hundred feet high, and no one seeing them for the 
first time would for a moment guess their true nature.
