of long, gently sloping, valleys militated against exten- 

 sive glaciation on the south and east of Mt. Field East. 

 But in places short glaciers formed and pushed down to 

 about the 3,000 feet level. 



One of these glaciers flowed down the valley now filled 

 by Lake Fenton. (See Plate X., Fig. 1.) This was a small flow, 

 arising from the limited snowfield on Kangaroo Moor and the 

 low hills immediately surrounding the lake, and flowing down 

 an old valley, of which Ihe Lady Barron Falls Creek Val- 

 ley is now the lower portion. The snowfield was too limit- 

 ed to supply a long ice-flow, and the glacier was probably 

 never more than a mile in length, and probably no wider 

 than we now see Lake Fenton. The ice pushed about a 

 quarter of a mile below the present shore of the lake. 

 The bank over which the Lake Fenton pack-track rises 

 just after the sixth mile peg represents the end of the- 

 moraine deposited by this glacier. 



The valley of the Lady Barron Falls Creek is bounded 

 by the precipitous sides of Seager's Look-Out to the east 

 and Mt. Monash to the west, forming a very sharp V, the 

 sides of which are strewn with a talus of enormous blocks 

 of diabase torn from their seats largely by the action of 

 frost, and tumbled down the slopes in a perfect wilderness 

 of huge rocks. Over the top of this valley the glacier 

 has deposited its moraine until now, looking from Kan- 

 garoo Moor through this gap, a distinct U-shaped valley 

 is seen. 



The ice appears to have retreated very slowly, but very 

 regularly, covering the bottom of the valley with glacial 

 till extending a quarter of a mile. The surface of 

 this moraine is very level, a noticeable fact on the walk 

 to Lake Fenton, and here and there boulders of all sizes 

 protrude from the reddish soil and gravels. The moraine 

 completely blocks the valley, and dams back Lake Fenton,, 

 stretching from a few yards across the overflow from the 

 lake right along the southern shore of the lake, and a 

 little distance on to a spur running down from Mt. Monash. 



The outlet from the lake at one time flowed over 

 the eastern end of the moraine, but in the course of time 

 it has washed the earth and lighter materials away from 

 the boulders, and now, except in flood time, runs out of 

 sight below an accumulation of loose rocks of all sizes. 



The eastern shore of Lake Fenton is strewn with a 

 mass of huge boulders, which have the appearance of
