Kent Plateau was named by the
Location
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
Several short glaciers run down from the plateau into Byrd Glacier. From southwest to northeast they are:
Zeller Glacier
80°55′S 156°30′E / 80.917°S 156.500°E. A glacier about 10 miles (16 km) long, flowing west-north-west to enter the south side of Byrd Glacier just north of Mount Fries. Named by US-ACAN for Edward J. Zeller, geologist at McMurdo Station, 1959–60 and 1960-61 seasons.[4]
Sefton Glacier
80°45′S 156°52′E / 80.750°S 156.867°E. Glacier about 10 miles (16 km) long, flowing into the south side of Byrd Glacier just west of Rundle Peaks. Named by the US-ACAN for Ronald Sefton, ionospheric physicist, a member of the Byrd Station winter parties of 1962 and 1964.[5]
Twombley Glacier
80°35′S 157°45′E / 80.583°S 157.750°E A glacier 6 miles (9.7 km) long, flowing from the north side of the Kent Plateau into the south side of Byrd Glacier. Named by US-ACAN for C.E. Twombley of the U.S. Weather Bureau, a member of the Little America V winter party, 1956.[6]
Brecher Glacier
80°42′S 157°28′E / 80.700°S 157.467°E. A broad glacier 5 nautical miles (9 km) long in the north
Judith Glacier
80°29′S 158°49′E / 80.483°S 158.817°E. Glacier about 9 miles (14 km) long, flowing from the vicinity of Mount Hamilton northeastward to enter Byrd Glacier just east of Mount Tuatara. Named by US-ACAN for Cdr. J.H. Judith, USN, commanding officer of the Edisto during USN OpDFrz 1964.[8]

Mount Hamilton
80°40′S 158°17′E / 80.667°S 158.283°E. A mountain, 1,990 metres (6,530 ft) high, standing at the east edge of Kent Plateau, 7 miles (11 km) south of Mount Tuatara. Discovered by the BrNAE (1901–04) and named for Admiral Sir Richard Vesey Hamilton, who served on Arctic voyages (1850–54) and was a member of the Ship Committee for this expedition.[12]
Cupcake Peaks
80°42′S 158°36′E / 80.700°S 158.600°E). Two rounded peaks, or nunataks, which rise to 1,391 metres (4,564 ft) 3 nautical miles (6 km) southeast of Mount Hamilton. The allusive name given by the Advisory Committee on Antarctic Names is suggestive of the appearance of the peaks.[13]

Nearby features to the west and north, along the southern edge of the Byrd Glacier, include from southwest to northeast, Keating Massif, Mount Fries, Zeller Glacier, Mount Rainbow, Sefton Glacier, the Rundle Peaks, Brecher Glacier, Mandarich Massif, Twombley Glacier, Blake Massif, Lowry Massif, Mount Tuatara, Judith Glacier, Mount Tadpole, the Miscast Nunataks and Couzens Saddle. Roberts Pike and Carr Crest are isolated features to the east of Lowry Massif.[3][14]
Keating Massif
81°00′00″N 156°34′00″E / 81°N 156.5666667°E. A rugged mainly ice-covered massif, 20 kilometres (12 mi) long, rising to approximately 2,370 metres (7,780 ft), and lying northwest. It is located at the southern edge of the head of Byrd Glacier. The feature includes Mount Fries and forms the southwestern boundary of
Mount Fries
80°57′S 156°36′E / 80.950°S 156.600°E A prominent peak, 1,985 metres (6,512 ft) high, standing just south of the mouth of Zeller Glacier and being one of the westernmost summits along the south wall of Byrd Glacier. Named by US-ACAN for Robert H. Fries, aurora scientist at the South Pole Station, 1963.[16]
Mount Rainbow
80°54′S 156°55′E / 80.900°S 156.917°E. A peak, 2,050 m, along the south side of Byrd Glacier, surmounting the broad ridge between Zeller and Sefton Glaciers. So named by the NZGSAE (1960–61) as the peak consists of multi-colored beds of sandstone with probable dolerite sitting on pink-green limestone.[17]
Rundle Peaks

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

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.

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]
