with Evidence Valley Creek. The distance to this point from 

 Townsend's Pass is about 4| miles, and we think it may safely 

 be inferred that the Snowy Valley was at one time filled with 

 ice to at least as far down as this. 



Before considering the possible thickness of ice in this valley it 

 will be advisable to describe the important collateral evidence in 

 the Lake Albina Valley. 



Lake Albina Valley. — The finest glaciated rock surfaces 

 hitherto observed by us are in the Lake Albina Valley. 



The upper end of the valley, where the evidences of past 

 glacial action are pronounced, is only about three-quarters of a 

 mile in length, the slope of the bottom of the valley being- 

 gradual for this distance, but below the north end of Lake Albina 

 plunging steeply down towards the Murray River. Traced to its 

 commencement the valley is found to begin on the north side of 

 Townsend's Pass (the pass over the main Dividing Range between 

 the Murray and the Snowy River watersheds, due south of Lake 

 Albina). The altitude (by aneroid) of this pass is 6,650 feet. 



From the base of the northern slope of this pass to the 

 northern end of Lake Albina the bottom of the valley is filled 

 with hummocky masses of moraine material, surmounted by large 

 granite erratics up to 20 feet in diameter, and it appeared to us 

 to contain more morainic material than any other of the valleys 

 examined by us on the Kosciusko Plateau, with the exception, 

 perhaps, of the Evidence Valley. 



The moraine drift has been carried beyond the north end of 

 Lake Albina, and to some height up the eastern slope of the 

 valley, numerous large erratics of granite having there invaded 

 the area of the slate (phyllite) formation. These can be seen in 

 the distance in a photograph by one of us (Mr. E. F. Pittman). 

 (Plate X., fig. 8). 



Several small tarns are situated near the upper end of the 

 moraine debris, south of Lake Albina. Lake Albina itself owes 

 its origin to a moraine dam. This has been cut through by the 

 creek, and huge boulders derived from it now fill the bed of the
