The following classification of the land-ice of South Victoria Land has been 

 taken from Mr Ferrar's Report on the Field Geology of the Expedition, pp. 63, 64. 



1. Ice-sheet or Inland-ice applies to a mass of ice which covers a continental 



area of land. 



2. Local Ice-cap, the ice covering partially or wholly a limited land mass. 



3. Piedmont-glaciers are formed by ice crowding on to a coastal plain at the foot 



of a mountain range. 



4. Glaciers of Greenland type, or Ice-streams, drain an ice-sheet and end in 



the sea. 



5. Glaciers of Norwegian type flow from a large firnfield down well-defined 



valleys (fjords). 



6. Glaciers of Alpine type, Valley-glaciers, drain small intermontane basins and 



never reach the sea. 



7. Cliff-glaciers are broken glaciers of the above types. 



8. Hanging -glaciers are collections of snow and ice in corries. 



9. Ice-slabs are glacier remnants, resulting from ice-recession.
