(7) Cliff-glaciers* Re-cernented glaciers, Glaciers remanies are broken glaciers of 
the above types, which having a Thalweg, too steep in places to hold the 
ice, have areas of bare land separating the firnfields and the final tongues 
of ice which they produce. 
(8) Hanging glaciers, f Corrie-glaciers, Hangegletscher, are masses of snow and ice 
lying in cirques, corries or hanging valleys. The ice in these disappears by 
melting, or by ablation, or by both processes, before the glacier can reach the 
main ice-stream. 
(9) Ice-slabs are apparently peculiar to South Victoria Land, and are glaciers 
which, from the cessation of ice-supply, have slipped away from their 
former firnfield. 
(10) Icebergs J are common to both the polar regions, and may be appended to 
this list as products of the breaking-up of all glaciers which reach the sea. 
1. The Inland-ice. 
We have seen that the mountain-belt of South Victoria Land, quite 60 miles 
in breadth, buttresses a firnfield of vast but unknown extent. This ice-sheet has a 
horizontal upper surface, which on the west of the Royal Society Range has an 
elevation of 7650 feet. It Hows eastward through the range in a deep-sided valley 
which bifurcates downwards in a most peculiar way. In the Prince Albert Range 
the flow passes between nunataks, which are sometimes 20 miles long, in arms ten 
miles across. The nunataks are usually broadside on to the present flow. The 
passes are shorter than they are broad, and have a striking similarity to those 
on the west coast of Greenland. § 
In the ranges lying south of the Royal Society Range are deep and narrow 
channels termed “ inlets ” by Captain Scott. These channels are ice-filled, but 
lie much below the level of the adjacent mountain-ranges and have very steep 
sides. A theodolite showed only a very slight rise in the horizon along these, 
so that if the Hinterland rises at all high it must lie many miles west of the 
coast. The Inland-ice flows through these channels to feed the Ross Piedmont 
or Ice-sheet. 
The surface of the Inland-ice, where observed, consists entirely of soft snow- 
powder and shows no gradual passage through granular snow to compact ice. 
The soft snow-powder, being readily taken up by wind and whirled about, is 
removed in bulk and transported bodily into the Ross Sea.
