formation, which rests in turn on a foundation of granite rock. To the left of the 

 section are two long and deep glacier valleys. The right-hand valley, the Fry 

 Glacier Valley, is of the nature of an outlet glacier. When we were looking directly 

 up it we could see that it cut its way right across the horst, and apparently 

 ascended to the snow-fields at the back of the plateau. It is a long, narrow glacier 

 with straight, clean-cut rock walls, resembling in general appearance those of the 

 Ferrar Glacier.

 Penck Glacier northwards, showing a continuation of the piedmont ice with stratified rocks, 

 probably Beacon Sandstone, to the right. Piedmont ascends to over 1000 feet before it reaches

had evidently been intensely glaciated, as also has Tripp Island, off the mouth of 

 the Penck Glacier.* 



The latter appeared more to resemble an alpine glacier. It was very deeply 

 entrenched, but did not appear to cut right through the horst. 



Plate XV. we owe to the faithful copying with great accuracy by Mr. K. 

 Craigie of a negative much too faint to yield a satisfactory print. The glacier 

 behind the cyclometer of the sledge is the Penck Glacier. The Fry Glacier 



* It is doubtful whether this sketch, made in 1908, is correct in showing Tripp Island so close 

 to the piedmont. Priestley found in 1912 that Tripp Island was surrounded by sea ice, and about 

 2 miles distant from the nearest piedmont. There can be no doubt that the piedmont has shrunk 

 noticeably between 1908 and 1912.
