32 GLACIAL REMAINS IN THE NATIONAL PARK, 



a talus. Perhaps they are the frost-disintegrated remains 

 of a small cliff carved out by the glacier, but more pro- 

 bably are a continuation of the talus slopes on the side 

 of Seager's Look-Out, to be seen below the lake, the bottom 

 portion of which has been covered by glacial and lacustrine 

 deposits, now forming the floor of Lake Fenton. On the 

 western side of the lake there is a narrow shore, which 

 shows slight traces of glaciation, before the ground rises 

 sharply to the hill behind. 



Kangaroo Moor, especially along the northern shore 

 of the lake, shows traces of glacial till, and Wombat Moor 

 is covered with erratics, many of tremendous size. Probably 

 a feeder flowed from the snowfields north of Mt. Monash 

 into the Lake Fenton glacier, and about 200 yards from 

 Quiet Corner along the Lake Dobson track there is a ridge 

 of boulders crossing the moor that seems to be a small 

 moraine. Evidently just prior to the vanishing of the 

 glaciers, a small ice flow found its way down from Mt. Mon- 

 ash, scattering debris over Wombat Moor, but melting before 

 it reached Lake Fenton. 



(b) The Lake Nicholls Area. (See Plates IX. and XL), 



The southern slope of Mt. Field East drops precipitous- 

 ly some 700 feet from the edge of the plateau. At an alti- 

 tude of 3,200 feet lies a considerable ledge on the moun- 

 tain side, on v/hich lie Lake Nicholls and Seattle's Tarn. 

 Circling round the south and south-west of Lake Nicholls, 

 and separating that lake from Beattie's Tarn, is a very 

 considerable ridge of morainal material. This rises sharply 

 from the eastern end of Lake Nicholls to a height of 200 

 feet above the level of the lake, and forms a round hill 

 iDetween this lake and Beattie's Tarn, from which hill the 

 ridge dips in a wide U northward until it rests on the 

 diabase buttress of Mt. Field East. This U can be dis- 

 tinguished with equal clearness from either Beattie's Tarn 

 or Lake Nicholls. It is extremely steep on both sides, and 

 has the appearance of a pressure ridge, consisting of boulder 

 clay, containing some huge rocks, and probably largely 

 caused by the glacier passing materials up from below 

 and piling them over this bank. 



There were probably several small glaciers flowing 

 down the several creases in the otherwise abrupt escarp- 

 ment of Mt. Field East, the largest of which, flowing down 

 the gully at the head of Lake Nicholls, on reaching the
