800 GLACIER ACTION ON MOUNT KOSCIUSKO PLATEAU, 



decomposition. Nowhere in the valley of the Crackenback or at 

 its head could I find any traces of grooved or scratched pebbles, 

 or any features that would suggest i^ocAes Moutonnees. Neither 

 could I find any trace of Moraines. Very often masses of boulders 

 might be noted, evidently transported from higher ground; but 

 neither the Ijoulders, nor the detrital masses of which thev form 

 a part, gave the least indication of glacial action. Undoubtedly, 

 as Mr. Helms puts it, " rocks showing rounded, concave, and 

 level surfaces "* are abundant. But most certainly none of these 

 features can without strong collateral evidence be attributed to 

 glacial action. From the Crackenback Valley I travelled along 

 the main range to the foot of Mt. Kosciusko. Naturally I turned 

 to the Wilkinson Valley for some of the evidence that Dr. 

 Lendenfeld found so abundant. I camped here for a week, 

 but long before that time elapsed I was forced to the conclusion 

 that Dr. Lendenfeld was utterly mistaken in attributing any of 

 the features in the Wilkinson Valley to glacial action. Thus far 

 Mr. Helms agrees with me. Dr. Lendenfeld is very definite in 

 his statement that he " found glacier-polished rocks in several 

 places."! Mr. Helms could see none of these poli.shed surfaces 

 in the W^ilkinson Valley. Let me add that I could see none of 

 them either. In despair at finding any of the traces that were 

 so evident to Dr. Lendenfeld, I decided to visit other places 

 indicated on Mr. Helms' map as affording the " glacier traces." 

 This map appears as PL xviii. in Proceedings of this Society (2nd 

 Series), Vol. viii. Map in hand I, journeyed to Lake Albina, on 

 which lake Mr. Helms shows a peninsula jutting into the lake, 

 and he colours this peninsula blue, as affording evidence of "glacier 

 traces." Here is a photograph showing the lake and the peninsula. 

 (PI. xxxvii., fig. 1 ). In the picture there is nothing to be seen sugges- 

 tive of ice action. On examining the place itself there is absolutely 

 nothing to be found indicative of ice-action. There is in fact no 

 feature about the lake, the cliff", or the talus at its base, that may
