The Nash Range (81°55′S 162°0′E / 81.917°S 162.000°E / -81.917; 162.000) is a mainly ice-covered coastal range in the Churchill Mountains of Antarctica.

Location

[edit]

The Nash Range is 40 nautical miles (70 km) long, bordering the west side of the Ross Ice Shelf between the Dickey and Nimrod Glaciers.[1] The Dickey Glacier flows north into Beaumont Bay to the north of the range.[2] To the south of Bridge Pass, the Algie Glacier flows south along the west edge of the range to enter Nimrod Glacier, which passes round the southern end of the range.[3] The Holyoake Range lies to the southwest of the Nash Range.[3] The Surveyors Range is to the northwest.[2]

The range was named by the Ross Sea Committee for Walter Nash who, as Leader of the Opposition and later as Prime Minister of New Zealand, gave strong support to New Zealand participation in the Commonwealth Trans-Antarctic Expedition, 1956–58.[1]

Topography

[edit]

The Nash Range is composed of metagreywacke intruded by granite. It trends north-north-west from Cape Wilson in the south to Beaumont Bay in the north. The average height is about 4,500 feet (1,400 m). Mount Christmas is the highest peak, at 5,608 feet (1,709 m). The west and east sides of the range have steep scarps, with granite cliffs 2,000 to 3,000 feet (610 to 910 m) high, and sharp ridges spurs of metagreywackes along the coast.[4]

Ross Sea Committee for the Hon. R.M. Algie who, as Minister in Charge of Scientific and Industrial Research, gave his strong support to the N.Z. party of the CTAE, 1956-58.[5]
