Pointer Nunatak
Pointer Nunatak () is a conspicuous nunatak, 1,245 m, immediately east of Wedge Ridge in the west part of the Shackleton Range. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and so named because it is an important landmark on the route from Blaiklock Glacier to Stratton Glacier Stratton Glacier () is a glacier 20 nautical miles (37 km) long, flowing north from Pointer Nunatak and then northwest to the north of Mount Weston, in the Shackleton Range.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ...

Wedge Ridge
Wedge Ridge () is a conspicuous rock ridge, 1,145 m, near the head of Blaiklock Glacier and immediately west of Pointer Nunatak in the west part of the Shackleton Range. First mapped in 1957 by the CTAE.

Shackleton Range
The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to , it extends in an east–west direction for about between the Slessor and Recovery glaciers. The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16. Surveys The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft. Geology The Haskard Group and Turnpike Bluff Group rest unconformably on the Archean-Middle Proterozoic Shackleton Range Metamorphic Complex. The Ordovician-Early Devonian Blaiklock Glacier Group (475 Ma) also unconformably overlies the Shackleton Range Metam ...

Commonwealth Trans-Antarctic Expedition
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...

Blaiklock Glacier
Blaiklock Glacier () is a glacier long, flowing north from Turnpike Bluff, then northwest to Mount Provender and Mount Lowe in the western part of the Shackleton Range, Antarctica. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition (CTAE), and named for Kenneth V. Blaiklock, the leader of the advance party of the CTAE in 1955–56 and a surveyor with the transpolar party in 1956–58.

Stratton Glacier
Stratton Glacier () is a glacier 20 nautical miles (37 km) long, flowing north from Pointer Nunatak and then northwest to the north of Mount Weston, in the Shackleton Range. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and named for David G. Stratton, surveyor and deputy leader of the transpolar party of the Commonwealth Trans-Antarctic Expedition in 1956–58.
