The David Glacier (75°19′S 162°00′E / 75.317°S 162.000°E / -75.317; 162.000) is a glacier over 60 nautical miles (110 km; 69 mi) long, flowing east from the polar plateau through the Prince Albert Mountains to the coast of Victoria Land, Antarctica. It enters Ross Sea between Cape Philippi and Cape Reynolds to form the floating Drygalski Ice Tongue. It is the most imposing outlet glacier in Victoria Land. It is fed by two main flows which drain an area larger than 200,000 square kilometres, with an estimated ice discharge rate of 7.8 +/- 0.7 km/year. The David Glacier was discovered by Ernest Shackleton's "Northern Party," in November 1908, under the leadership of Prof. T.W. Edgeworth David, of Sydney University, for whom the feature was named.
Location
The David Glacier flows eastward in a broad stream that gradually narrows towards the coast. The northern flow drains from Talos Dome to the Ross Sea, but the main branch of the stream is fed by a network of tributaries which drain a common area of the inner plateau around Dome C and converge in a spectacular icefall known as the David Cauldron. Mount Kring, Mount Wood and the Martin Nunataks are to the north of the David Glacier's head. The Ricker Hills and Trio Nunataks are to the south. The Hollingsworth Glacier joins the David Glacier from the southeast to the east of the Trio Nunataks. East of this the glacier descends through the David Cauldron, then continues east. It is joined from the north by the Woodberry Glacier, flowing between Evans Heights and Mount Fearon, and past Mount Priestley to the east. In its lower section the David Glacier flows past the D'Urville Wall, Mount Neumayer and Cape Philippi to the north, in the Prince Albert Mountains, and past Hughes Bluff and Cape Reynolds to the south, to form the Drygalski Ice Tongue, which enters the Ross Sea between Relief Inlet to the north and Geikie Inlet to the south.
Features
Features of the glacier, its tributaries and the terrain through which they flow include:
Mount Kring
74°59′S 157°54′E / 74.983°S 157.900°E / -74.983; 157.900. A sharply defined nunatak on the northern margin of the upper reaches of David Glacier, 13 nautical miles (24 km; 15 mi) southwest of Mount Wood. Previously uncharted, it was used (with Mount Wood) as a reference for establishing a United States Antarctic Research Program (USARP) field party on Nov. 6, 1962. Named by D.B.McC. Rainey of the Cartographic Branch of the New Zealand Dept. of Lands and Survey for Staff Sergeant Arthur L. Kring, USMC, navigator on many United States Navy VX-6 Squadron flights during the 1962–63 season when New Zealand field parties received logistic support by that squadron.
Mount Wood
74°49′S 158°24′E / 74.817°S 158.400°E / -74.817; 158.400. An isolated nunatak lying northward of David Glacier and 13 nautical miles (24 km; 15 mi) northeast of Mount Kring. Named by D.B. McC. Rainey of the Cartographic Branch of the New Zealand Dept. of Lands and Survey. Named after the foster parents of Staff Sgt. Arthur L. Kring, USMC, navigator with the United States Navy VX-6 Squadron which provided logistic support for the NZGSAE (1962–63).

Mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1956–62. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Robert D. Martin, USGS topographic engineer at McMurdo Station, 1961–62.
Hollingsworth Glacier
75°33′S 159°57′E / 75.550°S 159.950°E / -75.550; 159.950. A broad glacier of low gradient, draining the vicinity east of the Ricker Hills and flowing northeast to enter David Glacier just east of Trio Nunataks. Mapped by USGS from surveys and United States Navy air photos, 1956–62. Named by US-ACAN for Jerry L. Hollingsworth, meteorologist with the South Pole Station winter party, 1966.
David Cauldron
75°20′S 160°50′E / 75.333°S 160.833°E / -75.333; 160.833. An icefall of turbulent iceblocks on the David Glacier. Named by the Southern Party of the NZGSAE, 1962–63, in association with David Glacier.
Woodberry Glacier
75°06′S 161°38′E / 75.100°S 161.633°E / -75.100; 161.633. A small tributary glacier flowing south between Evans Heights and Mount Fearon to the north side of David Glacier. Mapped by USGS from surveys and United States Navy air photos, 1956–62. Named by US-ACAN for Barry D. Woodberry, ionospheric physicist with the South Pole Station winter party, 1966.
D'Urville Wall
75°16′S 162°13′E / 75.267°S 162.217°E / -75.267; 162.217. A great glacier-cut wall of granite which rises to 720 metres (2,360 ft) high and forms the north wall of David Glacier near its terminus. Discovered by the British Antarctic Expedition, 1907–09, under Shackleton. He named this feature for Admiral Jules Dumont d'Urville.
Cape Philippi

A rock cape rising abruptly to 490 metres (1,610 ft) high along the coast of Victoria Land, marking the north side of the terminus of David Glacier. Discovered by the British Antarctic Expedition, 1907–09, under Shackleton, who named this feature for Emil Philippi, distinguished geologist, who was a member of the GerAE, 1901–03, under Drygalski.
Hughes Bluff

Discovered by the British Antarctic Expedition, 1907–09, under Shackleton, who probably named this feature for Jeremiah (John) N. Reynolds, an American who long agitated for exploration of the Antarctic, and who was one of the principal promoters of the United States Exploring Expedition, 1838–42.
