Further Exploration of Centre Valley 



from beneath the curtain-like termination of this that 

 the water rushed as a foaming torrent. 



Part of the ice-front, that in the centre of the 

 glacier, terminated in a thin edge, beyond which the 

 surface rose in a very gradual slope, being strewn with 

 angular stones and furrowed by very numerous stream 

 courses, cut deeply into the ice, and receiving the waters 

 produced by the melting of the glacier in the bright sun- 

 shine. 



The glacier at its termination did not cover more 

 than half the width of the valley, there being wide tracts 

 on either side covered with angular gravel disposed in 

 long, steep-sided ridges parallel to the valley sides. 

 These were lateral moraines, and one of them could be 

 seen in course of formation. The angular stones and 

 sand from the surface of the glacier could be seen sliding 

 down its sloping side and accumulating as a talus at the 

 foot of the slope, and it was not difficult to see that the 

 result of a further recession of the ice would leave this 

 talus in a sharp-topped ridge similar to those which 

 flanked the ice for considerable distances on both sides 

 of the valley. 



At intervals between this area of lateral moraines 

 and the gorge the ice-front was nearly vertical, and here 

 the glacier could be seen to consist of definite layers, 

 giving the whole a banded structure. At one point a 

 small stream emerged from an archway under the glacier, 

 and the beautiful pale-blue colour of the ice could be 

 plainly seen, the interior of the ice-cave being like some 

 beautiful fairy grotto. Here the character of the stones 

 and boulders was in marked contrast to that of those 

 in the lateral moraines, they being for the most part
