The cliffs of Cape Crozier form the eastern extremity of Ross Island. Rising 

 to a height of 800 feet, they consist largely of columnar basalt "and a yellow 

 trachytic rock occurring in irregular lenticles in the mass of the cliff'." (Ferrar, 

 Nat. Hist. Rep., vol. i., p. 10.) 



In Fig. 1 may be seen evidences of the recession of the Barrier ice in the 

 neighbourhood of this disturbed corner. The fragments of ice-cliff still attached to 

 the rock, at a height of 40 or 50 feet along the foot of the cliffs, are remnants of the 

 main Barrier sheet which must quite recently have occupied the bay.
