20 GLACIAL REMAINS IN THE NATIONAL PARK, 



probably extended down the sides to an altitude of 3,000 

 feet. The great snowfields that accumulated on the more 

 level portions of the highlands fed glaciers that pushed down 

 the valleys. 



The chief of these ice rivers flowed down the Broad 

 Eiver; one branch fed by the snowfields extending from 

 Mt. Monash to Mt. Mawson pushed straight down the val- 

 ley. It was soon joined by a second flow of equal size from 

 Lake Seal Valley, fed by accumulations of snow on the 

 ridges above that lake, and later by a third branch flowing 

 down from I^ake Newdegate to Lake Webster. Together, 

 these pushed four or five miles farther down the valley 

 of the Broad River, and during its prime the glacier must 

 have been seven miles in length, and over half a mile wide, 

 and 300 feet deep. It extended to a point 2,400 feet above 

 sea-level, where it melted, and the water was carried off 

 down* the Broad River to the Derwent. In the track of this 

 glacier we find the most extensive evidences of ice action 

 to be found in the Park. 



On each side of this considerable glacier existed a group 

 of smaller ice-streams. To the east, growing from snow- 

 fields on Mt. Field East, Kangaroo Moor, and on the eastern 

 side of Wombat Moor, a glacier flowed down the valley now 

 occupied by Lake Fen ton, breaking up at about 3,000 feet 

 above sea-level, not far below the present shore of Lake 

 Fenton, at about the six mile peg on the track from the 

 entrance to the Park. 



Farther to the east, under the slope of Mt. Field East, 

 two other glaciers developed. The larger, flowing south- 

 east, was responsible for Lake Nicholls and Lake Rayner, 

 and the other flowed south-west over the present site of 

 Beattie's Tarn. Neither of these reached much lower than 

 3,000 feet, and both were small, as they were situated on 

 the eastern, and, therefore, the dry and warm, side of the 

 ranges. 



The western group comprised two glaciers of con- 

 siderable extent flowing in opposite directions, one south- 

 ward through the Belcher-Belton Valley, and the other 

 north through the Hayes Valley. These were fed by the 

 snow from the lofty crags that surrounded them. The 

 Belcher-Belton glacier was a composite one, and flowed 

 for about two miles down the valley of the Humboldt Creek 

 to an altitude of about 2,900 feet. The other was only about
