COAST BETWEEN CAPE IRIZAR AND THE NORDENSKJOLD TONGUE 69 



Fig. 24 is a continuation of the preceding section, showing the coastal 

 piedmont aground for a farther distance of about 10 to 12 miles southwards. 



Mount George Murray is about 20 miles distant, and 17 miles back from the 

 coast-lme. The width of the coastal plain, on which the piedmont rests, is here 

 about 15 miles. (See Fig. 26.) 



The Harbord Ice Tongue is about 30 feet in height at its eastern end, about 

 1 mile wide, and 5 miles long. It will be noticed that there is a very wide breach

in the plateau between Mount George Murray and Mount Howard, through which 

 gap the ice from the inland plateau passes seawards. 



The total aggregate length of coast seen in these two sketches is about 28 miles. 

 The coastal piedmont is about 15 miles wide. 



The outlines of the hills to the left of Mount Smith suggest that they have been 

 intensely glaciated right over their summits. The next sketch of the part of the 

 coast which follows immediately to the south shows its configuration near the 

 Mawson Glacier. In the foreground, just back from the coast, is the glacier ice of 

 the piedmont. This gradually passes on to an intensely glaciated rock terrace.

seen at the centre of the sketch. This terrace is much overspread with large 

 patches of morainic material (Fig. 25). 



The sharp peak at the back of this terrace is Mount Murray ; it is evidently 

 formed of a granitic rock, and its outlines showed evidence of its having been 

 glaciated over its summit. It is of the natui'e of a tind. The wide gap between 

 Mount Smith and Mount Gauss, at the bottom of which lies the Mawson Glacier, 

 shows clear evidence of former much more extensive glaciation. The shore end of 

 Nordenskjold Ice Tongue is shown just to the left of Charcot Bay. 



This part of the coast appearing to be of special interest, several sketches were 

 made of it.
