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. Named by the N.Z. party of the CTAE (1956–58) for B.R. Law, Deputy-Chairman of the Ross Sea Committee.[12]
