PLATE XLIV. MOUNT TERROR FROM THE SOUTH-EAST. 



From photographs by R. W. SKELTON (Sk. 194-197 inclusive, ^-plates), Oct. 20, 

 1902; looking north-westward from the surface of the Barrier ice. 

 (Map B.) 



Mount Terror, like Mount Erebus, is completely glacier-covered on its southern 

 side, yet not so deeply but that innumerable ice-falls and ice-cascades appear at 

 various points, suggesting rocky cliffs and precipitous irregularities beneath. It is a 

 comparatively frequent occurrence for avalanches to fall over these cliffs with a 

 muffled roar and a cloud of snow-powder closely resembling an explosion. 



But on the north-eastern slopes the whole appearance alters, and much dark 

 rock appears from top to bottom, since the force of the southerly gales makes 

 the settlement of snow impossible. Sastrugi or snow-dunes are formed at this 

 corner of a great depth and extent, hard as ice, and chiselled out to sharp edges 

 like white marble. Something is seen of these in the accompanying photograph, 

 but in places the irregularity is such that travelling with sledges becomes 

 quite impossible. 



On the extreme right is a subsidiary crater, the Knoll, which looks down 

 upon the Emperor Penguins' rookery bay, at the junction of the Cape Crozier 

 cliffs and the Barrier ice-cliffs. 



The crater at the summit of Mount Terror is 10,755 feet above sea-level. 

 The camp is situated on a continuation of land-ice lying between the slopes of 

 Mount Terror and the pressure ridges of the floating Barrier ice. Probably at 

 this point the pressure ridges allow of tidal movement, and take the place of 

 a more distinct and recognisable tide-crack.
