288 SCOTT’S LAST EXPEDITION 
(d) The Great Piedmont glacier between Granite Harbour 
and New Harbour (77° 20’). 
Each of these regions presented its own peculiar topography, 
and the four were diverse enough to embody almost the whole 
cycle of glacial erosion within their domain.

Knob Head Mountain, but were originally distinct parallel gla-

ciers draining the ice plateau. As one marches up the Ferrar 
Glacier and notes its crevasses and ice falls, one wonders what 
the rock floor is really like—under the ice river. Just 5 miles to 
the north is another glacier which furnishes the answer to this 
question, for the Taylor Glacier now stops short 25 miles from 
the sea, and in Dry Valley we see how all the other valleys will 
appear when the ice age shall pass away from Antarctica. 
Starting from New Harbour at the mouth of Dry Valley, 
the latter presents a typical catenary cross-section. A splendid 
pair of walls with the characteristic slope of 33° defines the gla- 
cier trough. There is no large terminal moraine near the sea, 
which seems to denote a fairly uniform and perhaps rapid retro- 
cession of the glacier. About 6 miles from the coast a narrow 
defile appears on the north side, but the rounded valley floor rises
