moraine in which diabase boulders alternate with quartzite 

 ones. The moraine has not at any place complstely dammed 

 the valley, and there is no lake here. At the time this 

 glacier was in the field several other ict? flows mu^t have 

 moved a few miles out on to the plain from the numenms 

 small recesses along the south-western face of the mountain. 

 These have not left, any well-defined cirques and could never 

 have been extensive, but the plain near the foot of the 

 mountain is littered with morainal material, amongst which 

 diabase boulders are common, and these must have been 

 carried some miles. 



Apparently the crest of the more northern of the two 

 western spurs stood out from the ice at this period, and 

 the glaciers that flowed along each side have sapped back 

 into the quartzite and produced a fine comb ridge. For the 

 whole length of this spur its top culminates in a kni^e-like 

 edge which the sapping efi'cct of the ice has cut through at 

 regular intervals, with the result that the top is crowned 

 with a series of pinnacles rising precipitously 100 feet or 

 more from the general line of the summit of the ridge. Its 

 northern face shows some fine ice sculpturing, and is cut 

 by several cirques. The Port Davey track skirts the foot 

 of an escarpment 1,000 feet in height that appears to be a 

 cirque wall. The end of the spur is divided into several 

 minor features by cirques that have cut deeply into it and 

 have, by enlarging their heads, thrown into relief the rock 

 sentinels at the entrance to the cirques described by Pro- 

 fessor Hobbs (Hobbs, 1921) which now stand out as quite 

 prominent peaks. The second spur appears to have been 

 under the ice for a long period and possesses a round con- 

 tour without cliff's or irregularities, which anyone ascending 

 the mountain finds to be a great advantage. 



Farther to the south lies the Lake Judd Cirque, which, 

 commencing at the south-west corner of the mountain, has 

 eaten right into the centre of the pre-glacial plateau and 

 nearly meets the western cirque just described. It is a 

 fine example of this glacial feature, that to such an extent 

 makes our mountain scenery. The floor of the cirque is 

 almost entirely occupied by Lake Judd, a handsome sheet 

 of water, perhaps two miles in length and a half a mile wide, 

 crescentic in shape and set in the very heart of the mountain, 

 with cliff's probably 2,000 feet high rising on three sides 

 almost vertically from its waters. To the north-east and 

 the south-east the cirque has enlarged its basin until it has 

 met other cirques and eroded the entire pre-glacial surface
