Mountain range in Antarctica
The Cobham Range (82°18′S 159°0′E / 82.300°S 159.000°E) trends in a northwest–southeast direction for about 20 nautical miles (40 km), standing west of Prince Philip Glacier in the southern part of the Churchill Mountains of the Ross Dependency, Antarctica.
Early exploration and naming[edit]
The Cobham Range was mapped by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1961–62, and named by the New Zealand Antarctic Place-Names Committee for a former Governor-General of New Zealand, Lord Cobham.
Geology[edit]
The range gives its name to the “Cobham Formation”.
This is a sequence of interlayered quartzite, marble and schist of the albite-epidote hornfels facies.
It is conformably overlain by greywacke and argillite of the Goldie Formation.
The Cobham Formation crops out in the south-west portion of the Cobham Range as a strip about 2–4 kilometres (1.2–2.5 mi) wide extending from west of Mount Kopere south to Gargoyle Ridge.
Glaciers[edit]
The Prince Philip Glacier runs south down the east side of the Cobham Range, and the Lucy Glacier runs southeast down the west side. They both feed the Nimrod Glacier, which flows to the northeast past the south end of the range.
Gray Glacier[edit]
82°23′S 159°35′E / 82.383°S 159.583°E.
A glacier in the Cobham Range, 6 mi long, lying south of Tarakanov Ridge and flowing southeast to merge with Prince Philip Glacier where the two join the Nimrod Glacier.
Named by the Holyoake, Cobham, and Queen Elizabeth Ranges party of the NZGSAE (1964-65) for M. Gray, postmaster and assistant radio officer at Scott Base, 1965.
Features[edit]
Geographical features from north to south include:
Frustration Ridge[edit]
82°12′S 158°38′E / 82.200°S 158.633°E.
Ridge forming the north end of the Cobham Range in the Churchill Mountains.
So named by the Holyoake, Cobham, and Queen Elizabeth Ranges party of the NZGSAE (1964-65) because although from below it looked a simple climb, great difficulty was
experienced in traversing it.
Schroeder Peak[edit]
82°15′S 158°37′E / 82.250°S 158.617°E.
Peak, 2,230 metres (7,320 ft) high, standing 3 miles (4.8 km) northwest of Mount Kopere in the Cobham Range.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1960-62.
Named by US-ACAN for James E. Schroeder, USARP glaciologist at Little America V, 1959-60.
Mount Kopere[edit]
82°17′S 158°51′E / 82.283°S 158.850°E.
Peak 1.5 miles (2.4 km) northwest of Lyttelton Peak in the central part of Cobham Range.
Named by the Holyoake, Cobham and Queen Elizabeth Ranges party of the NZGSAE (1964-65).
Kopere is the Maori word for arrow; the peak’s triangular cross section from most directions suggests an arrowhead.
Lyttelton Peak[edit]
82°18′S 158°56′E / 82.300°S 158.933°E.
The highest peak, 2,335 m, of the Cobham Range.
Mapped by the NZGSAE (1961-62) and given the family name of the former Governor-General of New Zealand, Lord Cobham. Not: Lyttleton Peak.
Tarakanov Ridge[edit]
82°19′S 159°24′E / 82.317°S 159.400°E.
A prominent ridge from the Cobham Range, between the Gray Glacier and Prince Philip Glacier.
Mapped by the USGS from tellurometer surveys and Navy air photos, 1960-62.
Named by US-ACAN for Gennady Tarakanov, Soviet exchange scientist, meteorologist at McMurdo Station, 1963.

82°24′S 159°30′E / 82.400°S 159.500°E.
High rock ridge forming the south end of Cobham Range in the Churchill Mountains.
So named by the Holyoake, Cobham, and Queen Elizabeth Ranges party of the NZGSAE (1964-65) because of the curiously wind-carved rock buttresses on top of the ridge.
