Mapped by the New Zealand party (1957-58) of the Commonwealth Trans-Antarctic Expedition and named for Professor R.S. Allan of the University of Canterbury, New Zealand.

Mount Allan Thomson
Mount Allan Thomson (-76.95°N, 161.71667°W) is a conspicuous mountain surmounted by a dark peak over 1,400 m which stands at the north side of Mackay Glacier, about 3 nautical miles (6 km) west of the mouth of Cleveland Glacier in Victoria Land. Charted and named by the British Antarctic Expedition (1910-13) for J. Allan Thomson, British geologist who assisted in writing the scientific reports of the British Antarctic Expedition, 1907-09.

Mount Allan
Mount Allan (-69.98333°N, -67.75°W) is the largest massif (1,600 m) in the Traverse Mountains, isolated to the north and south by low passes, on the Rymill Coast, Palmer Land. Named in 1977 by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Thomas J. Allan (1940-66), British Antarctic Survey (BAS) radio operator at Stonington Island, 1965-66, who lost his life while sledging with J.F. Noel near Tragic Corner, Fallieres Coast, in May 1966.

Allardyce Range
Allardyce Range (-54.41667°N, -36.55°W) is a mountain range attaining a maximum elevation of 2,935 m in Mount Paget, rising south of Cumberland Bay and dominating the central part of South Georgia. Although not shown on the charts of South Georgia by Cook in 1775 or Bellingshausen in 1819, peaks of this range were doubtless seen by those explorers. Named in about 1915, for Sir William L. Allardyce, Gov. of the Falkland Islands, 1904-14.

Allegheny Mountains (Antarctica)
Allegheny Mountains (-77.25°N, -143.3°W) is a small group of mountains 10 nautical miles (18 km) west of the Clark Mountains in the Ford Ranges of Marie Byrd Land. Discovered on aerial flights made in 1934 by the Byrd Antarctic Expedition, and mapped from aerial flights and ground surveys made by the United States Antarctic Service (USAS) (1939-41). Named by the USAS for Allegheny College, Meadville, PA, alma mater of Paul Siple, leader of the USAS West Base.

Allegro Valley
Allegro Valley (-71.3°N, 160.16667°W) is a steep-sided, glacier-filled valley indenting the east side of Daniels Range just north of White Spur, in the Usarp Mountains. The northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963-64, experienced fine weather here after several days of unpleasant travel; therefore, members named it after Milton's poem "L'Allegro" in antithesis with Penseroso Bluff, 14 nautical miles (26 km) to the north.
