The Enceladus Nunataks are a group of about eight nunataks scattered over a wide area at the head of the drainage basin of Saturn Glacier, in southern Alexander Island, Antarctica. They were mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. The group was named by the UK Antarctic Place-Names Committee from association with Saturn Glacier, Enceladus being one of the moons of the planet Saturn.
Coal Nunatak is a flat-topped rock mass with steep cliffs facing south, standing 2 nautical miles (4 km) southwest of Corner Cliffs on the southeast corner of Alexander Island, Antarctica. Lincoln Ellsworth first noted it from the air on November 23, 1935, and mapped it from photos obtained on that flight by W.L.G. Joerg. Observed from the northwest, only the summit protrudes above the coastal ice, and it was uncertain whether this was a peak on Alexander Island or an island in George VI Sound. Its true nature was determined by the Falkland Islands Dependencies Survey (FIDS) who visited and surveyed this nunatak in 1949. So named by FIDS for exposures of thin lenses of coal occur there.
Neptune Glacier is a glacier on the east coast of Alexander Island, Antarctica, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing east into George VI Sound and the George VI Ice Shelf to the south of Triton Point. Although Neptune Glacier is not located within the mountain range Planet Heights, the glaciers name derives from the mountain range along with many other nearby glaciers named after planets of the Solar System. There are also other nearby landforms named in association with these glaciers. The glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The mouth of the glacier was positioned in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Neptune following a Falkland Islands Dependencies Survey (FIDS) survey in 1949. The head of the glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.
The Corner Cliffs are a rocky mass surmounted by two flat-topped summits 1.5 nautical miles (3 km), immediately south of Saturn Glacier and lying 2 nautical miles (4 km) northeast of Coal Nunatak in the southeast part of Alexander Island, Antarctica. The rocks of these cliffs were hidden from the line of sight by intervening ice slopes to the west, but the two rock ridges forming the northwest shoulder of this feature were first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The cliffs were first surveyed in 1949 by the Falkland Islands Dependencies Survey, who gave this name to mark the point where the exposed rock of eastern Alexander Island turns from a north–south direction toward the southwest.
Jupiter Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (19 km) long and 5 nautical miles (9 km) wide at its mouth, which flows east into George VI Sound to the south of Ablation Valley. It was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition, and was named for the planet Jupiter by the Falkland Islands Dependencies Survey following their surveys in 1948 and 1949.
The Dione Nunataks are rock exposures at the head of Saturn Glacier, 9 nautical miles (17 km) west of Deimos Ridge in the southeastern part of Alexander Island, Antarctica. The nunataks appear to have been first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. They were remapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and were named by the UK Antarctic Place-Names Committee from association with Saturn Glacier, Dione being one of the satellites of the planet Saturn.
The Grossman Nunataks are a group of about a dozen nunataks in Ellsworth Land, Antarctica, rising 1,300–1,500 metres (4,300–4,900 ft) in elevation and running northwest–southeast for 18 nautical miles between the Lyon Nunataks and the Sky-Hi Nunataks. The group includes features from the Smith Nunataks and the Whitmill Nunatak in the northwest to Gaylord Nunatak and Neff Nunatak in the southeast.
Triton Point is a rocky headland at the east end of the high ridge separating Venus Glacier and Neptune Glacier on the east coast of Alexander Island, Antarctica. Lincoln Ellsworth first observed the coast in this vicinity from the air by on 23 November 1935, and it was roughly mapped from photos obtained on that flight by W.L.G. Joerg. The British Graham Land Expedition roughly surveyed Triton Point in 1936 by the Falkland Islands Dependencies Survey more accurately defined it in 1949. The United Kingdom Antarctic Place-Names Committee named it for its association with nearby Neptune Glacier, Triton being one of the satellites of the planet Neptune, the eighth planet of the Solar System.
Mount Phoebe is a mountain between the heads of Neptune Glacier and Saturn Glacier near the east coast of Alexander Island, Antarctica. The feature is situated at the junction of four radial ridges. The summit is a small mesa of conglomerate rising to about 300 m above the surrounding ice. First photographed by Lincoln Ellsworth, November 23, 1935, in the course of a trans-Antarctic flight and plotted from the air photos by W.L.G. Joerg. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) from association with Saturn Glacier after Phoebe, one of the satellites of the planet Saturn, the sixth planet of the Solar System.
Pickering Nunataks is a group of nunataks lying 2 nautical miles (3.7 km) southwest of Mount Phoebe and on the northeast side of Saturn Glacier, near the east coast of Alexander Island, Antarctica. The nunataks were photographed by Lincoln Ellsworth on November 23, 1935, in the course of a trans-Antarctic flight and were plotted from the air photos by W.L.G. Joerg. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) from association with Saturn Glacier after William H. Pickering (1858–1938), the American astronomer who discovered Phoebe, one of the satellites of the planet Saturn, the sixth planet of the Solar System.
Pagoda Ridge is a ridge with a small peak resembling a pagoda at the summit, located between Phobos Ridge and Deimos Ridge on the north side of Saturn Glacier, in southeast Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, during 1947 and 1948, and from surveying by the Falkland Islands Dependencies Survey, 1948–50. This descriptive name was applied by the United Kingdom Antarctic Place-Names Committee.
The Gannon Nunataks are a notable twin-peaked group of nunataks and several smaller rock outcrops, located between the northern end of the LeMay Range and the Lully Foothills, situated in the west-central portion of Alexander Island, Antarctica. The feature was photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey, 1960. It was named in 1977 by the UK Antarctic Place-Names Committee for Anthony E. Gannon, a British Antarctic Survey meteorological observer at Halley Station, 1970–72, a general assistant at Grytviken, 1972, and a builder at Stonington Island, 1973–75, who participated in a plane-table survey of northern Alexander Island, 1973.
Mimas Peak is a sharp conspicuous peak, rising to about 1,000 metres (3,300 ft) west of the head of Saturn Glacier and 9 nautical miles (17 km) west of the Dione Nunataks in the southeast part of Alexander Island, Antarctica. It was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The peak was sighted from a distance in 1949 by the Falkland Islands Dependencies Survey (FIDS) and roughly positioned. It was named by the UK Antarctic Place-Names Committee for its association with nearby Saturn Glacier, Mimas being one of the satellites of the planet Saturn. The peak and surrounding area were first mapped in detail from air photos taken by the Ronne Antarctic Research Expedition 1947–48, by D. Searle of the FIDS in 1960. Note that some maps incorrectly attach the name to a subsidiary and smaller peak off the east flank of the mountain. The name is actually attached to the highest peak in the Herschel Heights range.
Mercury Glacier is a glacier on the east coast of Alexander Island, Antarctica, 5 nautical miles (9 km) long and 2 nautical miles (4 km) wide, flowing east into George VI Sound between the Waitabit Cliffs and Keystone Cliffs. The glacier was probably first sighted from a distance by Lincoln Ellsworth, who flew near it and photographed segments of this coast on November 23, 1935. It was named by the UK Antarctic Place-Names Committee for the planet Mercury following rough surveys from George VI Sound by the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Although Mercury Glacier is not located within the Planet Heights, it is named in association with the heights along with many other nearby glaciers named after planets of the Solar System.
Mars Glacier is a glacier in the southeastern corner of Alexander Island, Antarctica, 6 nautical miles (11 km) long and 2 nautical miles (4 km) wide, flowing south into the George VI Ice Shelf. The glacier lies between Two Step Cliffs and Phobos Ridge. Mars Glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. It was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the UK Antarctic Place-Names Committee for the planet Mars, the fourth planet from the sun in the Solar System.
The Herschel Heights are a complex of nunataks of which Mimas Peak on the east is the highest, located southwest of the Enceladus Nunataks and near the head of Saturn Glacier in southeastern Alexander Island, Antarctica. The eastern part of this feature was photographed by Lincoln Ellsworth, November 23, 1935, in the course of his trans-Antarctic flight and was plotted from the air photos by W.L.G. Joerg. The heights were named by the UK Antarctic Place-Names Committee from association with Mimas and Enceladus, after Sir William Herschel, the British astronomer who discovered these two satellites of Saturn in 1789.
The Hyperion Nunataks are a group of about 10 nunataks lying south of Saturn Glacier and 8 nautical miles (15 km) west of the Corner Cliffs, in the southeastern part of Alexander Island, Antarctica. The group was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. It was surveyed in 1949 by the Falkland Islands Dependencies Survey, and so named by the United Kingdom Antarctic Place-Names Committee in association with nearby Saturn Glacier, Hyperion being one of the satellites of the planet Saturn.
Saturn Glacier is a glacier lying in southeast Alexander Island, Antarctica. The glacier is 15 nautical miles (28 km) long and 6 nautical miles (11 km) wide, flowing southeast into the George VI Ice Shelf of George VI Sound north of Corner Cliffs. Although the glacier is not situated within Planet Heights, its name derives from the nearby mountain range along with many other glaciers named after planets of the Solar System. The nunataks at the head of the glacier are also named after solar system features, for example the Enceladus Nunataks named for a moon of Saturn. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Saturn, the sixth planet of the Solar System.
Tethys Nunataks is a minor group of about five snow-free nunataks, lying 2 nautical miles (3.7 km) northeast of Stephenson Nunatak in the southeast corner of Alexander Island, Antarctica. Presumably first seen by Finn Ronne and Carl R. Eklund of the United States Antarctic Service who sledged through George VI Sound in 1940–41. Surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for association with nearby Saturn Glacier, Tethys being one of the satellites of the planet Saturn, the sixth planet of the Solar System.
Venus Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 6 nautical miles (11 km) wide at its mouth flowing east into George VI Sound lying between Keystone Cliffs and Triton Point. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935 and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for the planet Venus, the second planet of the Solar System.
