32 GEOLOGICAL NOTES ON KOSCIUSKO, 



a traveller following the usual route from Cooma via Jindabyne 

 and Boggy Plains to Kosciusko would be likely to see them. We 

 have, however, departed from this rule in the case of localities 

 where the evidence of glaciation is obscure, such areas being 

 treated of last. If, therefore, the evidences at Boggy Plains, 

 Pretty Point, and the flats near Porcupine Ridge and Betts' 

 Camp be passed over for the present, it may be assumed that the 

 observer has reached the right branch of the Snowy River near 

 its source. At the point where the track to Kosciusko from 

 Botts' Camp crosses the right branch of the Snowy River there is 

 a little morainic material in the valley bottom with a few tarns 

 lying higher up. 



At about 30 chains N.N.W. of this point, more in the direction 

 of the dray track than of the bridle track, the observer may 

 notice two moraines of rough angular granite blocks trailing down 

 from a spur of the Etheridge Range towards the Snowy River. 

 If this spur be now followed in a south-west direction for half a 

 mile, so as to rejoin the bridle track to Kosciusko, the observer 

 will see a fairly well marked lateral moraine just before the crest 

 of the ridge of the Etheridge Range is reached, at a point IJ 

 miles E. 33° N. from the Kosciusko Observatory. 



The altitude of the upper end of this moraine is about 6,660 

 feet, which is only a trifle lower than the upper end of the 

 moraine to be described later near Townsend's Pass (Lendenfeld) 

 in the Snowy Valley, these two being the highest moraines 

 observed by us in the Kosciusko region. Further along the 

 bridle track to Kosciusko a number of hummocky rock masses, 

 having all the appearance of Nunatahr^ form the capping of the 

 Etheridge Range. The altitude at the base of these is about 

 6,910 feet. The rocks up to the base of the Nunatakr show 

 evidence of having been much smoothed; and as grooved rocks 

 were seen by us near Mount Townsend up to a level of at least 

 6,850 feet, it is only reasonable to conclude that the ice surface 

 near these Nunatakr stood at an altitude of at least 6,910 feet. 

 Half a mile further along the bridle track is Ramshead Pass, about 

 one-quarter of a mile E.S.E. from the Kosciusko Observatory. The
