54 GEOLOGICAL NOTES ON KOSCIUSKO, 



Lendenfeld, would prefer to await more definite evidence before 

 concluding that the whole of the Kosciusko Plateau was formerly 

 buried in ice down to the level of Boggy Plains, or even lower. 

 At the same time the fact may be repeated here that there is 

 positive evidence that the glacier, descending from Mount 

 Twynam via Evidence Valley and Hedley Tarn towards the 

 Snow}' Kiver, came down to a level of about 5,800 feet above the 

 sea; and there is probable evidence of ice-action in this part of 

 the Snowy Valley even as far down as to about 5,500 feet above 

 the sea. 



The level of Pretty Point is about 5,990 feet and that of 

 Boggy Plains about 5,220 feet, so that the hypothesis of a wider 

 and older glaciation extending to Boggy Plains does not demand 

 the lowering of the limit which moving ice may have reached very 

 much below that to which we have positive evidence that it did 

 actually descend. 



If the Kosciusko Plateau ever underwent such a mer de glace 

 glaciation on a small scale, in Cainozoic time, probably the most 

 enduring evidence of it would be in the form of moraine p7-qfo7ide, 

 or even a terminal moraine some distance down the Snowy River 

 Valley. A more extended examination of this region may 3'^et 

 lead to the discovery of such evidence. 



IV. — Correlation of the Evidences of Glacial Action at 

 Kosciusko with those observed elsewhere 



Before drawing certain provisional deductions which are given 

 in our summary of this paper, it is necessar}'- to review briefly 

 similar evidences of glaciation in Cainozoic time in other parts 

 of the Southern Hemisphere. We have omitted the evidences, 

 described by some authors, from Victoria, as in the opinion of 

 Professor J. W. Gregory the evidences of Post-Tertiary glaciation 

 in such parts of Victoria as he has already examined are doubtful. 

 References, however, to the chief papers referring to this subject 

 are given in the appendix.
