The Kent Plateau (80°44′S 157°50′E / 80.733°S 157.833°E / -80.733; 157.833 (Kent Plateau)) is an ice-covered plateau in the northern extreme of the Churchill Mountains of Antarctica.

Name

[edit]

Kent Plateau was named by the Advisory Committee on Antarctic Names for Commander Donald F. Kent, U.S. Navy, logistics officer to Admiral Dufek at the outset of U.S. Navy Operation Deep Freeze I, 1955–56.[1]

Location

[edit]

The Kent Plateau is an ice-covered plateau, 12 miles (19 km) long and 4 miles (6.4 km) wide, extending northward from Mount Egerton and Kiwi Pass to the vicinity of Mount Hamilton.[1] The plateau is on the west of a ridge of mountains that runs north from Mount Durnford, dips at Kiwi Pass, then continues north from Mount Moa to Mount Hamilton along the east edge of the plateau.[2] To the west of the plateau along the southeast edge of the Byrd Glacier there is a chain of mountains broken by glaciers that flow down from the plateau region to Byrd Glacier.[3][2]

Glaciers

[edit]

Several short glaciers run down from the plateau into Byrd Glacier. From southwest to northeast they are:

Zeller Glacier

It is located at the southern edge of the head of Byrd Glacier. The feature includes Mount Fries and forms the southwestern boundary of Zeller Glacier. Named in honor of Colin Keating, who was the Secretary for Justice from 1997–2000. He had a distinguished 30 year career in the Public Service, mostly with the Ministry of Foreign Affairs and Trade, during which time he had a significant Antarctic focus through his work in the Legal Division and then as the Deputy Secretary responsible for Multi Lateral Affairs, which included the Legal and Antarctic Divisions. Later, as the Deputy Secretary responsible for Corporate Affairs, he retained authority for the Antarctic Policy Unit, at a time of considerable changes to the organizational structure of New Zealand Antarctic institutions from 1985 through to 1993. He provided much of the intellectual input behind New Zealand's work leading to the adoption of the Environment Protocol.[15]

Mount Fries

It stands between Brecher Glacier and Twombley Glacier, two southern tributaries to Byrd Glacier. The massif was named by the Advisory Committee on Antarctic Names after Captain (later Rear Admiral) Stevan Mandarich (1911–2001), U.S. Navy, Chief of Staff to Rear Admiral Richard E. Byrd on Operation Deep Freeze I, 1955–56.[19]

Blake Massif

A compact block of ridgelines without a prominent culminating summit, rising to approximately 1,800 metres (5,900 ft) on the south side of Byrd Glacier. The unit lies between Lowry Massif to the northeast and Mandarich Massif to the southwest. It was named in honor of Sir Peter Blake, who died in December 2001 during an environmental awareness expedition on the Amazon River. He was an exceptional sailor, and sought to raise worldwide awareness of environmental issues, to help protect life in, on and around the waters of the world. He sailed to the Antarctic Peninsula aboard the Seamaster in January 2001.[20][21]

Lowry Massif

[edit]

80°37′S 158°12′E / 80.617°S 158.200°E / -80.617; 158.200. A compact block of ridgelines without a prominent culminating summit, rising to about 1,800 metres (6,000 ft) on the south side of Byrd Glacier. The unit is 3 nautical miles (6 km) long and stands 3 nautical miles south-southwest of Mount Tuatara. A section of Shackleton Limestone was measured here by United States Antarctic Program geologist Edmund Stump on November 21, 2000. The massif is named after geologist Patrick H. Lowry, a member of Stump's Arizona State University field parties, 1977–78 and 1978–79, the latter season being in the Byrd Glacier area.[22]

Mount Tuatara

[edit]

80°34′S 158°20′E / 80.567°S 158.333°E / -80.567; 158.333. A mountain, 1,640 metres (5,380 ft) high, standing on the south side of Byrd Glacier, 7 miles (11 km) north of Mount Hamilton. Mapped by the NZGSAE (1960–61) who so named it because the long spiny summit ridge resembles a lizard.[23]

Mount Tadpole

[edit]

80°31′S 158°41′E / 80.517°S 158.683°E / -80.517; 158.683. A rounded and mostly ice-free mountain, about 1,000 metres (3,300 ft) high, with a narrow ridge running southwest from the main mass. The mountain is 4 nautical miles (7 km) east-northeast of Mount Tuatara on the south side of Byrd Glacier. So named by Advisory Committee on Antarctic Names (US-ACAN) because of the appearance of the mountain.[24]

Miscast Nunataks

[edit]

80°30′S 159°9′E / 80.500°S 159.150°E / -80.500; 159.150. A group of four nunataks which rise to 910 metres (3,000 ft) on the south side of Byrd Glacier. The outcrops lie between Mount Tadpole and Mount Madison. To their East is Couzens Saddle. The feature was geologically mapped as Dick Formation, a clastic, sandstone unit, by the New Zealand Geological Survey in 1960–61. The current name arose following remapping by United States Antarctic Program geologist Edmund Stump in 2000–01, and the determination that the entire outcrop is not sandstone but Shackleton Limestone.[25]

Couzens Saddle

[edit]

80°31′S 159°35′E / 80.517°S 159.583°E / -80.517; 159.583 A saddle rising to approximately 500 metres (1,600 ft), between the Miscast Nunataks and Mount Madison at west and east, and Byrd Glacier and Couzens Bay at north and south. It was named at the suggestion of the US Advisory Committee on Antarctic Names, in association with Couzens Bay, which was named by the New Zealand Geological Survey Antarctic Expedition (1960–61) in honor of Lieutenant Thomas Couzens, Royal New Zealand Air Force, who lost his life in a crevasse accident near Cape Selborne on 19 November 1959.[26]

Roberts Pike

[edit]

80°36′S 158°45′E / 80.600°S 158.750°E / -80.600; 158.750. A peak rising to 1,630 metres (5,350 ft), 5 nautical miles (9 km) southeast of Mount Tuatara. The culmination of several ridgelines, the summit commands a view of the drainage areas of Judith Glacier, Entrikin Glacier, and Couzens Bay. It was named by Advisory Committee on Antarctic Names (US-ACAN) after John "J.R." Roberts, a New Zealand mountaineer and field guide in 12 Antarctic seasons with United States Antarctic Program (USAP), 1987–88 to 2000–01, the last season in Churchill Mountains including work at this peak.[27]

Carr Crest

[edit]

80°38′S 159°23′E / 80.633°S 159.383°E / -80.633; 159.383. A rock summit rising to 1,200 metres (3,900 ft). It is 12 kilometres (7.5 mi) east south east of Roberts Pike and overlooks Couzens Bay due east. It was named in honor of Roderick Carr, a member of Shackleton's Expedition of 1914–17.[28]
