Polarstar Ridge ( 71°49′S70°29′W / 71.817°S 70.483°W ) is a jagged ridge, 4 nautical miles (7 km) long, trending southwest from The Obelisk in the Staccato Peaks, situated in the southern portion of Alexander Island, Antarctica. The ridge was named by the Advisory Committee on Antarctic Names (US-ACAN) after the Polar Star, the low-wing monoplane from which Lincoln Ellsworth, with pilot Herbert Hollick-Kenyon, discovered and photographed this ridge and the Staccato Peaks on November 23, 1935.

The Anare Mountains are a large group of mainly snow-covered peaks and ridges along the northern coast of Victoria Land, Antarctica. The group is bounded on the north and east by the Pacific Ocean, on the west by Lillie Glacier, and on the south by Ebbe Glacier and Dennistoun Glacier. They are north of the Concord Mountains and east of the Bowers Mountains.
Tucker Glacier is a major valley glacier of Victoria Land, Antarctica, about 90 nautical miles long, flowing southeast between the Admiralty Mountains and the Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which the Ebbe Glacier flows northwestward.
Toney Mountain is an elongated snow-covered shield volcano, 38 nautical miles long and rising to 3,595 metres (11,795 ft) at Richmond Peak, located 35 nautical miles southwest of Kohler Range in Marie Byrd Land, Antarctica.
The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies, with a height of 3,228 m (10,591 ft). Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains, together with other scattered peaks, form an arc about 420 km (260 mi) long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.
Staccato Peaks is a series of rock peaks extending 11 miles (18 km) in a north–south direction, rising to about 940 m with Hageman Peak being the highest peak of the Staccato Peaks, rising from the snowfields 20 miles (32 km) south of the Walton Mountains in the south part of Alexander Island, Antarctica. The peaks were first sighted from the air by Lincoln Ellsworth on November 23, 1935, and mapped from photos taken on that flight by W.L.G. Joerg. Remapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. The name, given by the United Kingdom Antarctic Place-Names Committee, refers to the precipitous and abrupt way in which the peaks rise from the surrounding snowfields and is associated with other musical names in the vicinity.
Hageman Peak is a montane landform pinnacle rising to about 940 metres (3,100 ft) at the northwest end of the Staccato Peaks in southern Alexander Island, Antarctica. The peak was photographed from the air by Lincoln Ellsworth in 1935, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Roger H. Hageman, U.S. Navy, an LC-130 aircraft commander during Operation Deep Freeze, 1969.
Probe Ridge is a prominent, snow-free, terraced ridge forming part of the north flank of Viking Valley, situated in the southeast portion of Alexander Island, Antarctica. The ridge was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1993 after the space probe which surveyed the planet Mars in 1976.
Gilliamsen Peak is a peak marking the southeast extremity of the Staccato Peaks in the south portion of Alexander Island, Antarctica. The peak was photographed from the air by Lincoln Ellsworth in 1935. Named by Advisory Committee on Antarctic Names (US-ACAN) after Lieutenant Commander Donald A. Gilliamsen, U.S. Navy, aircraft pilot, Squadron VXE-6, Operation Deep Freeze, 1969 and 1970.
The Porthos Range is the second range south in the Prince Charles Mountains of Antarctica, extending for about 30 miles in an east-to-west direction between Scylla Glacier and Charybdis Glacier. First visited in December 1956 by the Australian National Antarctic Research Expeditions (ANARE) southern party under W.G. Bewsher (1956-57) and named after Porthos, a character in Alexandre Dumas, père's novel The Three Musketeers, the most popular book read on the southern journey.
Rennick Glacier is broad glacier, nearly 200 nautical miles long, which is one of the largest in Antarctica. It rises on the polar plateau westward of Mesa Range and is 20 to 30 nautical miles wide, narrowing to 10 nautical miles near the coast. It takes its name from Rennick Bay where the glacier reaches the sea.
Bolten Peak is a small isolated peak 3 nautical miles (6 km) north of the Litvillingane Rocks, on the east side of Ahlmann Ridge in Queen Maud Land. It was mapped by Norwegian cartographers from surveys and from air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and from air photos by the Sixth Norwegian Antarctic Expedition (1958–59), and named "Bolten".
Welch Mountains is a group of mountains that dominate the area, the highest peak rising to 3,015 metres (9,892 ft), located 25 nautical miles north of Mount Jackson on the east margin of the Dyer Plateau of Palmer Land, Antarctica
Craig Ridge is a small rock ridge located close northeast of Polarstar Peak in the Sentinel Range, Ellsworth Mountains. It was named by the University of Minnesota Geological Party to these mountains, 1963–64, for James A. Craig, a helicopter crew chief with the 62nd Transportation Corps Detachment, who assisted the party. The geological party found a fossil leaf of the plant Glossopteris on the ridge.
Krieger Peak is a peak between Duffy Peak and The Obelisk in the central part of the Staccato Peaks, southern Alexander Island, Antarctica. The peak was photographed from the air by Lincoln Ellsworth in 1935, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Charles J. Krieger, U.S. Navy, an aircraft commander in Squadron VXE-6, Operation Deep Freeze, 1969 and 1970.
Duffy Peak is a peak southeast of Hageman Peak in the Staccato Peaks, southwest Alexander Island, Antarctica. Dargomyzhsky glacier extends and flows west from the base of Duffy Peak and enters the nearby Bach Ice Shelf. The peak was photographed from the air by Lincoln Ellsworth in 1935, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Joseph A. Duffy, a U.S. Navy aircraft pilot in Squadron VXE-6 during Operation Deep Freeze, 1969 and 1970.
Himalia Ridge is a ridge running east–west on the north side of the Ganymede Heights massif, north-east of Jupiter Glacier, in the east of Alexander Island, Antarctica. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. The ridge was named by the UK Antarctic Place-Names Committee following British Antarctic Survey geological work, 1983–84, after Himalia, a satellite of the planet Jupiter, in association with Jupiter Glacier.
Richter Peaks is a group of peaks rising to about 1,385 m located near the southern extremity of the Walton Mountains, situated in the central portion of Alexander Island, Antarctica. The peaks were named by Advisory Committee on Antarctic Names for Joseph J. Richter, United States Antarctic Research Program biologist, Palmer Station, 1965–66 and 1966–67.
Dargomyzhsky Glacier is an outlet glacier flowing west from Duffy Peak, in the central portion of the Staccato Peaks, central Alexander Island, Antarctica. The glacier extends across the central portion of Alexander Island and flows into the Bach Ice Shelf. The glacier was probably first photographed by Lincoln Ellsworth on November 23, 1935, and mapped from these photographs by W.L.G. Jeorg. This feature was named by the USSR Academy of Sciences in 1987 after Alexander Dargomyzhsky (1813–1869), Russian composer.
