Cobham Range
The Cobham Range (82°18′S 159°0′E / 82.300°S 159.000°E) is a mountain range in the Churchill Mountains of the Ross Dependency, Antarctica. It extends to the north of the Nimrod Glacier.
The Cobham Range trends in a northwest–southeast direction for about 20 nautical miles (40 km) in the southern part of the Churchill Mountains of the Ross Dependency, Antarctica. 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. The Holyoake Range is east of the Cobham Range on the east side of the Prince Philip Glacier. The Queen Elizabeth Range is south of the Cobham Range on the south side of the Nimrod Glacier.
The Cobham Range was mapped by the northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1961–62, and named by the New Zealand Antarctic Place-Names Committee for a former Governor-General of New Zealand, Lord Cobham.
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.
Geographical features from north to south include:
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.
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 the Advisory Committee on Antarctic Names (US-ACAN) for James E. Schroeder, United States Antarctic Program (USARP) glaciologist at Little America V, 1959-60.
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.
