PLATE LXXXL THE SHORE-ICE AT HUT POINT. 



FIG. 1. From a photograph by R. W. SKELTON (S. 38, 5" x 4" plate), Feb. 1, 1904. 

 FIG. 2. From a photograph by R. W. SKELTON (Sk. 112, |-plate), April 17, 1902. 



The shore-ice of South Victoria Land ends, as a rule, sharply with a 

 perpendicular ice-wall seawards ; a wall which varies from 3 to 300 feet in height. 

 Two types of shore-ice fringe may be distinguished 



1. Fringe due to frozen sea-spray. 



2. Fringe of glacier-ice adherent to the land. 



At Hut Point both fringes were exemplified from time to time ; the second is 

 pictured in these two photographs, which were taken when the sea was, and had 

 long been, frozen over. The broken pieces which have fallen on to the sea-ice are 

 detached by the constant movement that occurs along the tide-crack. 



Acting on the corniced fringe, which outgrows its stability afresh with every 

 snowstorm, this movement is incessantly at work to keep a sharp line of division 

 between the land-ice and the floating sea-ice.
