Tillite Glacier
Encyclopedia
Tillite Glacier is a tributary glacier
flowing northwest from Pagoda Peak
in Queen Alexandra Range
to join Lennox-King Glacier
north of Fairchild Peak
. So named by New Zealand Geological Survey Antarctic Expedition
(NZGSAE) (1961–62) because it contains outcrops of ancient moraine
(tillite), indicative of glacial action in remote Paleozoic times.
Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...
flowing northwest from Pagoda Peak
Pagoda Peak
Pagoda Peak is a sharp peak, 3,040 m, between the heads of Tillite and Montgomerie Glaciers, 3 nautical miles north of Mount Mackellar in Queen Alexandra Range. So named by the New Zealand Geological Survey Antarctic Expedition because of its shape....

Fairchild Peak

New Zealand Geological Survey Antarctic Expedition
The New Zealand Geological Survey Antarctic Expedition describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active in 1957-58 and again in 1958-59. The 1957-58 expedition went to the Ross Dependency and named the Borchgrevink Glacier...

Moraine
A moraine is any glacially formed accumulation of unconsolidated glacial debris which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past glacial maximum. This debris may have been plucked off a valley floor as a glacier advanced or it may have...
