Lennox-King Glacier is a large valley glacier, about 40 nautical miles (70 km) long that flows east into the Ross Ice Shelf.

Location

[edit]
Lower part of the glacier, to the southwest of the map.
Bowden Névé and part of the upper glacier, to the southeast of the map.
Law Glacier and Walcott Névé at the head of the glacier.

Lennox-King Glacier drains Bowden Névé and flows northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet and the Ross Ice Shelf.[1] The Law Glacier supplies ice to the Lennox-King Glacier, leading some glaciologists to refer to it as the Law/Lennox-King Glacier system or Law-Lennox-King glacier corridor.[2][3] Its mouth is south of the Robb Glacier[4] and west of the Beardmore Glacier.[5]

Lennox-King Glacier was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base, 1960.[1]

Mouth

Richards Inlet

[edit]

83°20′S 168°30′E / 83.333°S 168.500°E / -83.333; 168.500. A large ice-filled inlet at the mouth of Lennox-King Glacier, opening to the Ross Ice Shelf just southeast of Lewis Ridge. Named by the NZGSAE (1959–60) for R. W. Richards, a member of the Ross Sea Party of the Imperial Trans-Antarctic Expedition (1914–17), who assisted in laying depots as far south as Mount Hope for Shackleton's proposed crossing of Antarctica.[6]

Asquith Bluff

[edit]

83°30′S 167°21′E / 83.500°S 167.350°E / -83.500; 167.350. A prominent wedge-shaped rock bluff on the west side of Lennox-King Glacier, 4 miles (6.4 km) southeast of Mount Allen Young. Discovered by the BrAE (1907–09) and named "Mount Asquith" for Lord Oxford and Asquith, Prime Minister, 1908–16, who was instrumental in securing a grant from the United Kingdom Government to pay off the expedition's debts. Not: Mount Asquith.[7]

Vertigo Bluff

[edit]

83°35′S 167°00′E / 83.583°S 167.000°E / -83.583; 167.000. A prominent rock bluff, 1,950 metres (6,400 ft) high, located 4 miles (6.4 km) souith of Asquith Bluff on the west side of Lennox-King Glacier. Rock samples were collected at the bluff by John Gunner and Henry Brecher of the Ohio State University Geological Expedition, 1969-70. The name suggested by Gunner reflects the precipitous nature of the bluff face.[8]

Névé

[edit]

The glacier is fed by the Bowden Névé.[5][9] This in turn is fed by the Law Glacier and the Walcott Névé.[10]

A glacier about 10 miles (16 km) wide between the south end of Queen Elizabeth Range and the MacAlpine Hills, gradually descending east-north-east from the polar plateau to Bowden Névé.
