Commonwealth Range
Template:Short description Template:Infobox mountain range The Commonwealth Range (Template:Coord) is a north-south trending range of rugged mountains, Template:Convert long, located within the Queen Maud Mountains on the Dufek Coast of the continent of Antarctica. The range borders the eastern side of Beardmore Glacier from Keltie Glacier to the Ross Ice Shelf.Template:Sfn The range is southeast of the Queen Alexandra Range, which is to the west of the Beardmore Glacier. It is west of the Hughes Range and north of the Supporters Range and the Barton Mountains.
Discovery and naming
The range was discovered by the British Antarctic Expedition, 1907–09 and named by them after the Commonwealth of Australia, which gave much assistance to the expedition.Template:Sfn
Location
The Commonwealth Range runs from south to north along the east side of the Beardmore Glacier. Towards its southeast the Pain Névé feeds the Keltie Glacier, which flows southwest, then west, then north round the southern tip of the range to join the Beardmore Glacier. The Canyon Glacier forms just north of the Pain Névé and flows north along the east side of the range. Further north the Hood Glacier defines the east side of the range, which stretches to the Ross Ice Shelf. Features, from north to south, include Johnson Bluff, Flat Top, Mount Deakin, Mount Donaldson, Mount Macdonald to the east of Ludeman Glacier, a tributary of the Beardsmore, Mount Hermanson, Gray Peak, Dudley Head, Siege Dome, Dolphin Spur to the north of Hood Glacier, Mount Patrick, Wedge Face, Beetle Spur and Mount Cyril.Template:Sfn Further north are Celebration Pass, Mount Henry, Mount Harcourt and Mount Kyffin.Template:Sfn

Mount Donaldson
Template:Coord. A mountain, Template:Convert high, standing Template:Convert north-northeast of Flat Top and west of the head of Ludeman Glacier. Discovered and named by the British Antarctic Expedition, 1907–09.Template:Sfn
Mount Macdonald
Template:Coord. A peak, Template:Convert high, surmounting the massive north–south trending ridge between Ludeman Glacier and Pain Névé. Named by NZGSAE (1961–62) for the Hon. T.L. Macdonald, who was Minister of External Affairs and of Defence when the CTAE (1956–58) was being planned and who took a prominent part in obtaining New Zealand participation in the Antarctic.Template:Sfn
Mount Hermanson
Template:Coord. An ice-covered mountain in the Queen Maud Mountains, Template:Convert high, standing at the head of Cunningham Glacier, Template:Convert southwest of Gray Peak. Named by US-ACAN for Capt. J.M. Hermanson, USN, air operations officer, McMurdo Station, 1957–58; Chief of Staff to the U.S. Antarctic Projects Officer, 1959.Template:Sfn
Gray Peak
Template:Coord. A prominent rock peak, Template:Convert high, standing at the west side of Canyon Glacier, Template:Convert northeast of Mount Hermanson. Named by US-ACAN after Thomas I. Gray, Jr., Weather Central meteorologist at Little America V, 1958.Template:Sfn
Dudley Head
Template:Coord. A snow-covered, prominent ridge projecting into the east side of Beardmore Glacier, surmounted by several domes rising to Template:Convert, about Template:Convert south of Mount Patrick. Discovered and named by the British Antarctic Expedition 1907–09, and called "Mount Dudley" by Shackleton. The name was amended by US-ACAN in keeping with the appearance of the feature.Template:Sfn
Siege Dome
Template:Coord. A small, ice-covered prominence standing to the south of the head of Hood Glacier, close southeast of Mount Patrick. Named by the New Zealand Alpine Club Antarctic Expedition (1959–60) because while attempting to establish a survey station here, they met with an eight day snow storm.Template:Sfn
Dolphin Spur
Template:Coord. A broad ice-covered spur just east of Mount Patrick, descending north into the upper reaches of Hood Glacier. Its several rock outcrops when seen from lower levels of the glacier resemble a school of dolphins diving through the sea. Named by the New Zealand Alpine Club Antarctic Expedition, 1959-60.Template:Sfn
Mount Patrick
Template:Coord. A massive largely ice-covered mountain rising to Template:Convert high, just east of Wedge Face on the east side of the Beardmore Glacier. Discovered and named by the British Antarctic Expedition, 1907–09.Template:Sfn
Wedge Face
Template:Coord. A descriptive name for the prominent wedge-shaped rock spur that projects from Mount Patrick into the eastern part of Beardmore Glacier. This feature was almost surely observed by Shackleton's Southern Journey Party on its ascent of the Beardmore Glacier in December 1908. It was named by the South Pole Party of the British Antarctic Expedition, 1910–13, under Robert Scott.Template:Sfn
Beetle Spur
Template:Coord. A rock spur Template:Convert north of Mount Patrick. It descends from a small summit peak on the range to the east side of Beardmore Glacier. Probably first seen by Shackleton's Southern Party in 1908. The name is descriptive of the appearance of the spur when viewed from the west. Name suggested by John Gunner of the Ohio State University Geological Expedition, 1969–70, who collected geological samples at the spur.Template:Sfn
Mount Cyril
Template:Coord. An ice-covered mountain, Template:Convert high, standing Template:Convert south of Celebration Pass. Discovered and named by the British Antarctic Expedition, 1907-09 under Shackleton. Named for Cyril Longhurst, Secretary of the BrNAE (1901–04), who was best man at Shackleton's wedding.Template:Sfn
Celebration Pass
Template:Coord. A low pass through Commonwealth Range just north of Mount Cyril permitting passage between Beardmore Glacier and Hood Glacier. The pass was crossed on Christmas Day, 1959, by the N.Z. Alpine Club Antarctic Expedition (1959–60) and was named by them because of the festivities held to mark the day.Template:Sfn
Mount Henry

He was a traveling companion of Shackleton's on the voyage from England.Template:Sfn
Mount Robert Scott
Template:Coord. A small, flat, snow-covered mountain that rises over Template:Convert and is situated immediately south of Ebony Ridge. Discovered by the British Antarctic Expedition, 1907–09 under Ernest Shackleton, who named this feature for Capt. Robert F. Scott, RN. Shackleton had been a member of Scott's Southern Polar Party which reached 82|17'S on the British National Antarctic Expedition 1901–04).Template:Sfn
Ebony Ridge
Template:Coord. A coastal ridge Template:Convert long between Airdrop Peak and Mount Robert Scott at the north end of the Commonwealth Range. It consists of dark metamorphosed greywacke contrasting sharply with the predominate brown ochre of the weathered surface of the granitic intrusions forming nearby Mounts Kyffin and Harcourt. Descriptively named by the New Zealand Alpine Club Antarctic Expedition, 1959-60.Template:Sfn
Mount Kathleen
Template:Coord. A peak about Template:Convert high, being the central and highest summit of Ebony Ridge at the north end of Commonwealth Range. Discovered by the British Antarctic Expedition, 1907–09 under Sir Ernest Shackleton, who named this feature for his eldest sister. Template:Sfn
Airdrop Peak
Template:Coord. A twin-peaked mountain, Template:Convert high at the north end of Commonwealth Range. It is the first prominent feature in Ebony Ridge when approached from the northwest.
