356 EVIDENCES OF EXTENSIVE GLACIER ACTION AT MT. KOSCIUSKO, 



Prior to the time when the bifurcation took place the glacier 

 must have been considerably more massive and undoubtedly swept 

 over the rise at Pretty Point. This is plainly denionstrated by 

 the features met to the east and south-east of this elevation, and 

 has been already referred to. The interest involved in this is 

 that the ice-cap of the plateau must have been so enormous that 

 its limit could not well be brought within its confines, but must 

 have extended over a far greater area, for which, however, I am 

 not at present in a position to bring forward positive proof. 



All other features and indications met with on the plateau 

 could well be explained as having originated from local glaciation. 



The terminal moraines formed as the glaciers gradually receded 

 to the highest elevation will no doubt be met with in many more 

 localities than I was able to visit during my short stay in the 

 mountains. Those seen by me are marked on the map and need 

 no further description, excepting those I found close to one of the 

 highest peaks, which surpass all others in their perfect preservation 

 and unique formation. 



At the base of Mt. Twynam and in the valley to the south of 

 the Crummer Range, between this and the branch range that 

 runs out from the slate cap in an easterly direction towards the 

 Snowy River, these distinct and unmistakable evidences of glacier 

 action have been preserved. It seems almost as if the configura- 

 tions of the neighbouring mountains and ridges had been specially 

 designed for the purpose of retaining these evidences, and probably 

 no other locality in any part of the world can be found where 

 within so limited a space such a number of various evidences 

 testify to the former existence of ice, and piove the wonderful 

 changes it has made on the face of the earth. 



The small snow-fields hanging on the ledges and in the clefts of 

 the south-eastern declivities of Mt. Twynam faintly indicate still 

 how ages ago the snow piled up here and, transformed into masses 

 of solid ice, worked its way downward. This snow at the present 

 day never entirely disappears, and, though it only granulates and 

 is no longer transformed into ice, may be regarded as the last 

 remnant of former glacier formation. The pure liquid oozing
