48 GLACIOLOGY 



a process of betrunking, such as rivers suffer through coastal submergence, but 

 which is due in this case to deglaciation, the old ice drainage has become disinte- 

 grated and all these glaciers have become dismembered, with the exception perhaps 

 of the three with which we are now dealing,* and even of these three the Reeves 

 Glacier is all but, if not quite, dismembered from the Larsen-Drygalski Piedmont. 



The doubt in regard to this question of the exact line of demarcation, if any, 

 between the Reeves Piedmont and the Larsen Piedmont, is due to the fact that at 

 their margins each apron seems to pass gradually into old sea ice laden with the 

 snowfalls of many years. It is hard to say where glacier ice ends and sea ice begins. 

 There does appear to be a narrow strip of sea ice between the two piedmonts. 



The general asjiect of the coast-line is shown on Fig. 8 ; Evans Coves are 

 immediately to the right. In line with Mount Melbourne is a very deep inlet, which 

 is shown from a slightly difterent point of view. On Fig. 8 this is termed the 

 Campbell Glacier. Farther to the west is another deep inlet (called by the Scott 

 Expedition " Corner Glacier "). West again of this lies another deep inlet (called 

 by them Priestley Glacier), apparently occupied by a large glacier. Farther 

 still to the left is Mount Baxter, apparently of the order of about 8000 feet in 

 height ; and then to the left of this rises the majestic table-topped mountain. Mount 

 Nansen, 8000 feet high according to Mawson's survey, 8788 feet according to the 

 Discovery observations. This is capped with Beacon Sandstone, with apparently 

 limestone below the above formation, the whole resting on a massive foundation 

 of gneissic granite. Farther to the left is the wide, deeja valley of the Reeves 

 Glacier, with Teall Nunatak to the right front and Hansen Nunatak near 

 the centre. The massifs of Mounts Larsen, Gerlache, and Crummer, also mostly 

 of granite and entirely formed of crystalline rock, separate the Reeves fi'om the 

 Larsen Glacier on the left. Next the massifs of Mounts Bellinghausen, Gei'lache, 

 and Priestley separate the Larsen Glacier from the David Glacier. 



Time did not permit of an examination of the Campbell Glacier in 1908-9. It 

 seemed formed of very gently-sloping glacier ice for a great distance inland. 

 Corner Glacier probably contributes ice to the Nansen Piedmont, as does the 

 Priestley Glacier. 



The description of the ice formations between Terra Nova Bay and Geikie Inlet 

 may commence with the Drygalski Barrier, and thence we will proceed inland 

 up the glaciers. The Drygalski Ice Tongue is about 38 miles in length from 

 the shore to its seaward end. At 10 miles west of its extreme point it is 

 7 miles in width, at 20 miles west it is 13 miles in width, and along the shore 

 about 25 miles. 



Its general appearance, as seen from Cape Irizar, is shown on the following 

 sketch. 



* Lieutenant Campbeir.s pai'ty of Scott's recent Antarctic Expedition discovered and explored 

 several new glaciers contributing to this piedmont. They will shortly be described by Priestley.
