40 GEOLOGICAL NOTES ON KOSCIUSKO, 



the magnetic bearing from it to the Kosciusko Observatory is 

 200° 20'. 



The surface measures about 8 feet long by 2 feet wide at the 

 centre, and 1 foot wide at either end. It trends S. 5° E. and 

 N. 5° W., and its surface dips S. 10° W. at 10°. The whole 

 surface has been ground smooth, and is faintly striated. A 

 portion of this is now exhibited. 



The strise run N. 30° W., and S. 30° E., the strike side being 

 on the N.W., as might have been expected, as the valley here 

 falls from the N.W. towards the S.E. 



At a point nearly one-quarter of a mile south-east of the pre- 

 ceding is another striated rock surface of quartzite, of the nature 

 of a small roche moutonnee. The striae run from N.W. to S.E. 



The altitude of this is about 6,340 feet, whereas that of the 

 previous glaciated surface of quartzite is about 6,400 feet. The 

 level of the summit of the lateral moraine at its lower end is 

 6,510 feet, while that of the extreme upper end is 6,720 feet. 

 The Snowy Yalley below the 6,340 feet roche mouto7inee was not 

 examined by us in detail, excepting between a point due west of 

 Charlotte's Pass, at the junction of Club Lake (Harnett's Lake, 

 or Garrard Tarn), and the junction lower down of Evidence Valley 

 Creek with the Snowy River. Near the junction of Club Lake 

 Oreek with the Snowy River there is a well-marked terrace of 

 what appears to be redistributed moraine material on the right 

 bank of the Snowy River ; and several ice-scratched boulders 

 were picked up by us on the left bank of the Snowy, just above 

 its junction with Evidence Valley Creek, the latter having its 

 source in Lake Merewether (the Blue Lake). 



About 5,520 feet is the altitude by aneroid of the lowest spot 

 were such ice-scratched pebbles were found by us. This is the 

 lowest level at which any ice-scratched pebbles were observed. 

 It is of course possible that these were not in situ, but had 

 drifted down from higher levels. At the same time the gneissic 

 granite along this part of the Snowy Valle}^ shows almost certain 

 evidence of ice-wear, down to at least as far as the junction
