The glacier was photographed from the air by Captain W.M. Hawkes, United States Navy, on the historic first flight from New Zealand to McMurdo Sound on December 17, 1955.
An attempt to reconnoiter it by helicopter and to land a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) on it had to be abandoned when USS Glacier was damaged in pressure ice in December 1958. It was named by NZGSAE, 1958–59, as a tribute to the hazardous work of pilots and other airmen in Antarctic exploratory and scientific operations.[1]
Geography
The Aviator Glacier forms on the plateau of Victoria Land and flows in a generally southward direction along the west side of Mountaineer Range.
The head of the glacier is below Half-Ration Névé and the Forgotten Hills.
The Astronaut glacier forms to the south of Evans Névé and to the west of Retreat Hills and Mount Gobey.
It flows southwest to join the Aviator Glacier just west of Parasite Cone.[2]
The combined glacier flows past both sides of Navigator Nunatak.
The Aeronaut Glacier forms below Gair Mesa and flows north east, then east to join the Aviator Glacier south of Navigator Nunatak.
The Aviator Glacier flows southeast past the Arrowhead Range, where it is joined from the west by the Cosmonaut Glacier.
It is then joined from the northeast by the Pilot Glacier and turns south, past the Southern Cross Mountains to the west, from which it is joined by Cosmonette Glacier and Shoemaker Glacier, before turning southeast and forming the Aviator Glacier Tongue, which extends into Lady Newnes Bay to the east of Cape Sibbald and west of Wood Bay.[3]
Right tributaries
Tributaries from the right (west) include, from north to south:
Aeronaut Glacier
73°16′S163°36′E / 73.267°S 163.600°E / -73.267; 163.600.
A glacier of low gradient, about 25 nautical miles (46 km; 29 mi) long, draining northeast from Gair Mesa into the upper part of Aviator Glacier near Navigator Nunatak.
Named by the northern party of NZGSAE, 1962–63, to commemorate the air support provided by United States Navy Squadron VX-6, and in association with Aviator Glacier.[4]
73°37′S164°51′E / 73.617°S 164.850°E / -73.617; 164.850.
A tributary glacier in the Southern Cross Mountains, flowing east along the north side of Daley Hills to Aviator Glacier.
Named by the northern party of NZGSAE, 1962–63, in association with Cosmonaut and Aeronaut Glaciers and to commemorate the first woman astronaut.[6]
73°11′S164°22′E / 73.183°S 164.367°E / -73.183; 164.367.
A short, steep tributary glacier, flowing from the west and south slopes of Mount Overlord to the upper part of Aviator Glacier.
Named by the northern party of NZGSAE, 1962–63, in recognition of services rendered by pilots of United States Navy Squadron VX-6, and in association with nearby Pilot Glacier.[9]
Pilot Glacier
73°23′S165°03′E / 73.383°S 165.050°E / -73.383; 165.050.
A short, deeply entrenched tributary glacier in the Mountaineer Range, descending along the southeast side of Deception Plateau to enter Aviator Glacier.
Named by the northern party of NZGSAE, 1962–63, in recognition of services rendered by pilots of United States Navy Squadron VX-6 in Antarctica, and in association with Aviator Glacier.[10]
Other features
Half-ration Névé
73°01′S163°30′E / 73.017°S 163.500°E / -73.017; 163.500.
A large névé at the head of Aviator Glacier.
It is largely enclosed on the west side by the Mesa Range.
So named by the northern party of NZGSAE, 1962–63, because its resupply was delayed several days by blizzards and the party was limited to reduced rations.[11]
Forgotten Hills
72°59′S164°00′E / 72.983°S 164.000°E / -72.983; 164.000.
A small group of hills 6 nautical miles (11 km; 6.9 mi) southeast of the Intention Nunataks, at the west side of the head of Astronaut Glacier.
Named by the Southern Party of NZGSAE, 1966–67, because none of the three parties that had visited the area had time to examine these hills.[12]
Retreat Hills
72°59′S165°12′E / 72.983°S 165.200°E / -72.983; 165.200.
A group of hills at the south side of the head of Astronaut Glacier, along the south margin of Evans Névé.
So named by the Northern Party of NZGSAE, 1962–63, which had hoped to visit the hills, but was forced to beat a hasty retreat due to blizzards.[13]
Mount Gobey
72°58′S165°15′E / 72.967°S 165.250°E / -72.967; 165.250.
The highest mountain, 3,125 metres (10,253 ft) high, in the Retreat Hills, at the south margin of Evans Névé.
Climbed on Dec. 26,1966 by the Northern Party of NZGSAE, 1966–67, who named it for the party's field assistant, Dave .W. Gobey.[14]
Navigator Nunatak
73°15′S164°13′E / 73.250°S 164.217°E / -73.250; 164.217.
A large nunatak in the middle of the head of Aviator Glacier.
Named by the northern party of NZGSAE, 1962–63, because it is a good landmark for navigation and the name is also in association with Aviator, Pilot, and Co-pilot Glaciers, nearby.[15]
