PLATE XCVL KCETTLITZ GLACIER. 



FIG. 1 (Map B). From a photograph by A. B. ARMITAGE (A. 13, |-plate), Dec. 7, 

 1903 ; taken amongst the foot-hills at the southern end of Royal Society 

 Range. 



FIG. 2 (Map B). From a photograph by A. B. ARMITAGK (A. 14, ^-plate), Dec. 7, 

 1903; taken looking S.-W. towards Koettlitz Glacier from the foot-hills of 

 the Royal Society Range. 



Flowing eastward presumably from the inland ice, Koettlitz Glacier reaches 

 the sea-level between the southern end of the foot-hills of Royal Society Range to 

 the north, and Mount Morning and Mount Discovery to the south. It has a widtli 

 here of about eight miles, and continues from this point as a floating sheet of old 

 and increasingly weathered ice for a distance of 20 miles to the north along the 

 west side of M'Murdo Sound. 



Fig. 2 gives an idea of the extent of the weathering and disintegration of the 

 ice where the glacier snout first takes the water. Plates XCVII. to C. represent 

 the more advanced stages of weathering in the same ice-sheet farther north. 



In Fig. 1 is seen a small ice-tongue breaking away to the right from the parent 

 glacier, but now cut off from it by a ridge of rock, leaving it merely as an " ice- 

 slab." (See also Plate XCV.)
