GLACIERS OF GREENLAND TYPE.

prevent boulders rolling on to the surface, but well-developed moraines on it are 
seen where, on Minna Bluff and Black Island, the ice hugs the shore. These 
moraines, however, will be discussed later ; they are mentioned here as evidence 
that the ice-sheet does transport matter upon its surface. The movement of this 
piedmont seems to be comparatively rapid. Where measured by Lieutenant Barne at 
Minna Bluff, it was proved that a point moved through 608 yards * in thirteen and 
a half months. 
4. Glaciers of Greenland Type. (Plate III.) 
Under this head will be included such ice-streams as flow from the Inland-ice. 
In the Antarctic region this type of glacier is magnificently developed, and every 
gradation, from streams 5 to 60 miles long, and 5 to 10 miles wide, is to 
be seen. 
The Prince Albert Mountains exhibit features so similar to those of the west 
coast of Greenland that one description would suffice for both. Attention may, 
however, be drawn to the fact that the Greenland ice-streams end in fiords and 
come down between nunataks free from snow, whereas the ice-streams of the Prince 
Albert Range, though they may, perhaps, lie in fiords, project as if towards the 
edge of some coastal platform parallel to the mountains and well above the snow- 
line. The nunataks are wholly encircled by snow-slopes which are rather higher 
than the ice between them. The Ferrar Glacier is the only one that has been 
entirely traversed. Situated as it is on one of the highest ranges of South Victoria 
Land, it can hardly be considered quite typical, though steep inlets, which break 
directly from the coast and back into the high mountains, are peculiar to the whole 
resrion. The Ferrar Glacier has its source in the Inland- ice which lies at an 
O 
altitude of 7600 feet above sea-level to the west of the Royal Society Range. The 
head of the glacier is an amphitheatre some 10 miles across, and is marked off by a 
few small nunataks. The sudden rise to the Inland-ice is almost semicircular and 
stretches round from Depot Nunatak to the North-west Nunataks, with a curve 
concave to the east. This concave curve is marked by two parallel ice-falls, each 
about 500 feet high. From the foot of this fall the ice moulds itself to the valley, 
and between straight, parallel, and almost vertical, rock-walls flows off eastwards. 
Near Finger Mountain the valley widens somewhat, the north wall continues its 
straight course, but the south wall recedes irregularly to the base of Knob Head, 
and in this way leaves the depression at the Solitary Rocks (D 6 ) through which 
the ice from Windy Gully and South Arm enters. The ice from South Arm splits 
on a submerged water-shed and part flows first westwards and then northwards 
into the North Fork, while the rest, considerably supplemented by the discharge 
from the west of the Royal Society Range, fills up the East Fork, and eventually 
floats in the narrow fiord between the Lower Kukri Hills and the Northern Foothills.
