Peters Peak

Holyoake Range () is a mountain range in the Ross Dependency of Antarctice.
It is in the southern section of the Churchill Mountains, part of the Transantarctic Mountains System.

Location

The range extends in a northwest–southeast direction for about .
The Starshot Glacier runs east past the north of the range.
The Prince Philip Glacier runs south-south-east along the range's west side, and the Errant Glacier runs south-south-east along its east side. Both join the Nimrod Glacier, which runs northeast past the range's south end.
The Cobham Range is to the west, on the other side of the Prince Philip Glacier.

Topology and Geology

The Holyoake Range is a largely ice-free limestone massif.
It is wide on average.
The peaks rise steadily from Cambrian Bluff in the south at to Mount Hunt further north at .
The range rises abruptly from the bordering glaciers and has a subrectangular plan.
This suggests it gained its present form from block faulting during the Victoria Orogeny.

The bulk of the Holyoake and Swithinbank Ranges are made up of the Shackleton Limestone formation, which lies unconformably on an unweathered surface cut across beds of the Goldie Formation north of the Nimrod Glacier.
It includes the Cambrian limestone that crops out between the Byrd and Nimrod Glaciers and in the upper Beardmore Glacier.

Name

The Holyoake Range was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the Rt. Hon. Keith Holyoake who, first as Minister of Agriculture, then as Prime Minister, and later as Leader of the Opposition, gave strong support to New Zealand participation in the Commonwealth Trans-Antarctic Expedition of 1956–58.

Glaciers

Prince Philip Glacier

.
Glacier flowing south for about between Cobham and Holyoake Ranges into Nimrod Glacier.
Named by the NZ-APC for Prince Philip, Duke of Edinburgh, husband of Queen Elizabeth II.

Errant Glacier

.
Glacier, long, which lies on the east side of Holyoake Range and drains south into Nimrod Glacier.
This glacier offered a route to the southern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1960–61) when they journeyed north from Nimrod Glacier in December 1960.
Named by them to describe the zigzag route of the party in traveling on the glacier in search for a route north.

Features

Geographical features from north to south include:

Mount Richter

.
A mountain rising to between Gutenberg Glacier and upper Starshot Glacier in north Holyoake Range, Churchill Mountains.
The mountain is north of Cerberus Peak.
Named after Charles Francis Richter, American physicist, California Institute of Technology, 1930–70; in collaboration with Beno Gutenberg, 1935, he developed the Richter Scale which bears his name, used to measure the magnitude of earthquakes.

Cerberus Peak

A prominent peak, high, at the head of Prince Philip Glacier, northwest of Hunt Mountain. The name was suggested by the Holyoake, Cobham and Queen Elizabeth Ranges Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1964-65. Named after Cerberus, three-headed canine guardian of the gate to Hades in Greek mythology.

Castle Crags

.
Prominent jagged peaks north of Hunt Mountain, on the ridge extending north from the Holyoake Range.
Named by the NZGSAE (1964–65) for their castellated appearance.

Hunt Mountain

.
Mountain, high, which stands in the north part of the Holyoake Range and is its highest point.
Mapped by the southern party of the NZGSAE (1960-61) and named for Capt. P.J. Hunt, RE, leader of the party. Not: Mount Hunt.

Stark Ridge

.
A narrow ridge that extends from the east part of Hunt Mountain, and trends north for to the sharp north-north-east turn in Starshot Glacier. Several summits rise from the ridge which separates Sivjee Glacier and Mansergh Snowfield. Named by Advisory Committee on Antarctic Names (US-ACAN) after Antony A. Stark, Smithsonian Astrophysical Observatory, Cambridge, MA; U.S. Antarctic Project (USAP) principal investigator for the Antarctic submillimeter telescope and remote observatory at the South Pole, 1991-2002.

Adams Bluff

.
A bluff standing north of Peters Peak in the Holyoake Range of the Churchill Mountains.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1960–62.
Named by US-ACAN for Paul L. Adams, USARP meteorologist at Byrd Station, 1961–62, 1962–63, and at McMurdo Station, 1963-64, 1964-65.

Peters Peak

.
Snow-covered peak, high, standing northof Melrose Peak in the central part of Holyoake Range.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1960-62.
Named by US-ACAN for Merrill J. Peters, USARP field assistant, 1962–63.

Melrose Peak

A peak 4 mi S of Peters Peak in the Holyoake Range.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1960–62.
Named by US-ACAN for Robert L. Melrose, USARP meteorologist at Hallett Station, 1963–64.

Cambrian Bluff

.
Prominent bluff jutting into the north side of Nimrod Glacier and forming the south end of the Holyoake Range.
Named by the southern party of the NZGSAE (1960–61) because the bluff is faced with vast seams of pink and white marble.

Nearby features

Mansergh Snowfield

.
A snowfield feeding the central portion of the Starshot Glacier, separating the Surveyors and Holyoake Ranges.
Seen by the Holyoake, Cobham and Queen Elizabeth Ranges party of the NZGSAE (1964-65) and named for G. Mansergh, geologist with the party.
