;?0 NOTES ox MT. ANNE ANT) THE WKM1 KIYER VALIJJY. 



Judd Cirque and a plateau of quartzite between it and the 

 former of this pair. Between these two cirques, the Lake 

 Judd Cirque and the one on the eastern side of the moun- 

 tain, is a peak which provides a good example of a young 

 glacial horn. The cirques have met or all but met all round 

 it and have started to cut down the comb ridges, leaving 

 this mass of mountain standing well above the surrounding 

 cols, which are in process of being lowered, although the pro- 

 cess was not a quarter of the way towards completion when 

 the glaciers vanished. 



These glaciers ended where we now see their terminal 

 moraines, but the water flowing from them carried much 

 material with it. To the east this was washed down the 

 comparatively rapid Weld to the sea, but to the west the 

 many streams emerging from the glaciers' ends spread their 

 deposit over the flat plain already in existence, caused by 

 the previous ice invasion. They thus formed large areas of 

 glacial outwash aprons. Ix, is these masses of rock and 

 gravel strewn by numerous glacial streams over the older 

 glacial valleys that form the great buttongra^s plains of 

 Western and South-Western Tasmania. 



High up in various parts of the plateaux at about the 

 4,000 feet level and a little higher are several small cirques, 

 some containing mountain tarns. These are evidently due 

 to glacial action as described in the Field Ranges by Pro- 

 fessor Griffith Taylor (Taylor, 1921). On the top of the 

 main plateau there is a very perfectly formed and easily 

 recognisable pair of cirques eating into each side of the 

 quartzite patch before described and nearly cutting it in 

 two, and several lakelets are to be seen to the south-east of 

 the head of the Lake Judd Cirque. 



A few other evidences of past glacial action were 

 observed. To the south of Mt. Anne on the face of th« 

 quartzite plateau opposite the mountain could be seen four 

 small tarns, the largest of which, a.s has been mentioned, 

 has been called Smith's Tarn. These are all of glacial 

 origin and are splendid examples of small cirques. Smith's 

 Tarn rivalling the (so-called) Crater Lake on Cradle Moun- 

 tain. The ice descended by a rock stairway to the basin 

 of the tarn a few hundred feet below it, and thence probably 

 to the valley of the Anne River. 



The old moraine from Mt. Mueller noticeable from the 

 Port Davey track is described by Mr. Twelvetrees (Twelve- 

 trees, 1908), and although evidence of glacial action is not 

 otherwise obvious, the glacial theory of the origin of this
