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.
Bartók Glacier is a glacier, 7 nautical miles (13 km) long and 3 nautical miles (6 km) wide, flowing southwest from the southern end of the Elgar Uplands in the northern part of Alexander Island. It was first photographed from the air and roughly mapped by the British Graham Land Expedition in 1937, and more accurately mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. It was named by the UK Antarctic Place-Names Committee after the Hungarian composer Béla Bartók.
Nichols Snowfield is a snowfield, 22 nautical miles (41 km) long and 8 nautical miles (15 km) wide, bounded by the Rouen Mountains and Elgar Uplands to the east and Lassus Mountains to the west, in the north part of Alexander Island, Antarctica. The snowfield was first sighted from the air and roughly mapped by the British Graham Land Expedition (BGLE) in 1937. Mapped in detail from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the RARE for Dr. Robert L. Nichols, head of the Department of Geology, Tufts University, and senior scientist of the Ronne expedition.
Crescent Scarp is a conspicuous, north-facing escarpment of rock and ice cliffs, rising to 1,400 metres (4,600 ft) on the south side of Fleming Glacier in northern Palmer Land. It was roughly surveyed from the ground by the British Graham Land Expedition in 1936-37, and photographed from the air by the United States Antarctic Service in 1940 and the Ronne Antarctic Research Expedition in 1947. It was resurveyed by the Falkland Islands Dependencies Survey in 1958, and named descriptively.
Sverre Peak is a small peak 0.5 nautical miles (0.9 km) off the north end of Pettersen Ridge in the Conrad Mountains of Queen Maud Land. Discovered and photographed by the German Antarctic Expedition, 1938-39. Mapped by Norway from air photos and surveys by the Norwegian Antarctic Expedition, 1956–60, and named for Sverre Pettersen, steward with Norwegian Antarctic Expedition, 1957-58.
Delius Glacier is a glacier, 6 nautical miles (11 km) long and 2 nautical miles (4 km) wide, flowing west from the Elgar Uplands into Nichols Snowfield, in the northern part of Alexander Island, Antarctica. It was first seen from the air and roughly mapped by the British Graham Land Expedition in 1937. It was more accurately mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and from U.S. Landsat imagery of February 1975. It was named by the UK Antarctic Place-Names Committee after Frederick Delius, the British composer.
Perplex Ridge is a ridge, rising over 915 m, composed of four rocky masses separated by small glaciers, extending 6 nautical miles (11 km) northeastward from Lainez Point along the northwest side of Pourquoi Pas Island, off the west coast of Graham Land. First sighted and roughly charted in 1909 by the French Antarctic Expedition under Charcot. It was surveyed in 1936 by the British Graham Land Expedition (BGLE) and in 1948 by the Falkland Islands Dependencies Survey (FIDS). So named by FIDS because of confusion in attempting to identify this ridge from earlier maps.
Everson Ridge is a ridge extending from Jebsen Point to Tioga Hill on Signy Island. It was named by the UK Antarctic Place-Names Committee after Inigo Everson, a British Antarctic Survey biologist on Signy Island, 1965–66.
Pearson Spur is a spur extending southeast from Elgar Uplands toward the head of Sibelius Glacier, situated in the northern portion of Alexander Island, Antarctica. Photographed from the air by Ronne Antarctic Research Expedition (RARE) in 1947, roughly mapped from air photographs by Falkland Islands Dependencies Survey (FIDS) in 1959, and surveyed by British Antarctic Survey (BAS), 1973-77. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1980 after Martin Robert Pearson, BAS glaciologist, 1970–73, who worked on Alexander Island, in years 1971 and 1972.
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.
Gerontius Glacier is a glacier flowing north from the Elgar Uplands into Tufts Pass in northern Alexander Island, Antarctica. It was so named by the UK Antarctic Place-Names Committee in 1977, association with the nearby uplands, from The Dream of Gerontius, a work for chorus, solo voices and orchestra by Edward Elgar.
Hamna Icefall is an icefall which descends to the south end of Hamna Bay immediately east of Hamnenabben Head, on the coast of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Japanese Antarctic Research Expedition, 1957–62, and named by them in association with Hamna Bay.
Hariot Glacier is a glacier flowing northwest along the south side of Morgan Upland before turning west into the northern portion of the Wordie Ice Shelf, along the west coast of the Antarctic Peninsula. It was roughly surveyed by the British Graham Land Expedition, 1936–37, and the upper reaches were photographed from the air by the Ronne Antarctic Research Expedition, 1947. The glacier was surveyed from the ground by members of the Falkland Islands Dependencies Survey who travelled along it in December 1958, and it was named by the UK Antarctic Place-Names Committee after Thomas Hariot, an English mathematician who pioneered new methods of navigation under the patronage of Sir Walter Raleigh.
Stanwix Peak is a distinctive peak (2,240 m) which surmounts the south side of the head of Astapenko Glacier in the Bowers Mountains. The peak was used as a reference object by surveyor S. Kirkby, with the ANARE, 1962. Named by ANARE for Captain John Stanwix, helicopter pilot with the expedition.
Ring Rock is a rock lying 3.7 kilometres (2 nmi) southeast of Nost Island at the head of Holme Bay. Mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and named Ringoya. First visited in 1956 by an ANARE sledging party; they found that the term "rock" better describes this feature.
Lasher Spur is a prominent mountain spur trending northwest from the Kelvin Crests, 4 nautical miles (7 km) east-northeast of the Triune Peaks, Fallières Coast, Antarctica. The spur was photographed from the air by the Ronne Antarctic Research Expedition, 1947, and the U.S. Navy, 1966, and was surveyed by the Falkland Islands Dependencies Survey, 1958. It was named in 1977 by the Advisory Committee on Antarctic Names for Lieutenant William J. Lasher, U.S. Navy, an LC-130 aircraft commander in Operation Deep Freeze, 1969 and 1970.
Rotz Glacier is a tributary glacier 9 nautical miles (17 km) long and 2 nautical miles (3.7 km) wide. It flows west from Wakefield Highland, central Antarctic Peninsula, into Airy Glacier at a point due south of Mount Timosthenes. Photographed by Ronne Antarctic Research Expedition (RARE) on November 27, 1947. Surveyed by Falkland Islands Dependencies Survey (FIDS) in December 1958 and November 1960. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Jean Rotz, 16th century French chartmaker and writer on the principles of navigation, who designed an elaborate magnetic compass and became hydrographer to King Henry VIII in 1542.
