The Framnes Mountains is a group of Antarctic mountain ranges in Mac. Robertson Land, to the south of the Mawson Coast. The range is surrounded by, and largely covered by, an ice sheet.

Isdalsegga Ridge is a rock ridge surmounted by Pinegin Peak, forming the east wall of Isdalen Valley in the Südliche Petermann Range of the Wohlthat Mountains, Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39. It was replotted from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named "Isdalsegga" in association with Isdalen Valley.

Aurdalen Valley is a small moraine-covered valley between Grakammen Ridge and Aurdalsegga Ridge, in the Petermann Ranges of the Wohlthat Mountains. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, re-plotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named "Aurdalen".

Kapellet Canyon is a canyon with steep rock and ice walls indenting the eastern side of Jøkulkyrkja Mountain, in the Mühlig-Hofmann Mountains of Queen Maud Land. It was plotted from surveys and aerial photographs by the Sixth Norwegian Antarctic Expedition (1956–60) and named Kapellet.

Jutulstraumen Glacier is a large glacier in Queen Maud Land, Antarctica, about 120 nautical miles (220 km) long, draining northward to the Fimbul Ice Shelf between the Kirwan Escarpment, Borg Massif and Ahlmann Ridge on the west and the Sverdrup Mountains on the east. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Jutulstraumen. More specifically jutulen are troll-like figures from Norwegian folk tales. The ice stream reaches speeds of around 4 metres per day near the coast where it is heavily crevassed.

It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, replotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named Asimutbreen.

Bystrov Rock is a prominent rock lying 1 nautical mile (2 km) south-southeast of Isdalsegga Ridge in the Südliche Petermann Range of the Wohlthat Mountains. It was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60; remapped by the Soviet Antarctic Expedition, 1960–61, and named after Soviet paleontologist A.P. Bystrov.

<span class="mw-page-title-main">Gruber Mountains</span> Mountains of Antarctica

The Gruber Mountains are a small group of mountains consisting of a main massif and several rocky outliers, forming the northeast portion of the Wohlthat Mountains in Queen Maud Land, Antarctica. They were discovered and plotted from air photos by the Third German Antarctic Expedition (GerAE), 1938–39, under Alfred Ritscher. The mountains were remapped by the Sixth Norwegian Antarctic Expedition, 1956–60, who named them for Otto von Gruber, the German cartographer who compiled maps of this area from air photos taken by the GerAE. This feature is not to be confused with "Gruber-Berge," an unidentified toponym applied by the GerAE in northern the Mühlig-Hofmann Mountains.

The Östliche Petermann Range is one of the Petermann Ranges, trending in a north–south direction for 15 nautical miles (28 km) from Per Spur to the Gornyye Inzhenery Rocks, in the Wohlthat Mountains of Queen Maud Land. It was discovered and plotted from air photos by German Antarctic Expedition of 1938–39, and so named by them for its eastern location in the Petermann Ranges.

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.

Kubbestolen Peak is a bare rock peak, 2,070 metres (6,800 ft) high, at the northwest end of Vinten-Johansen Ridge in the Kurze Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Kubbestolen.

Pervomayskaya Peak is a peak, 2,795 m, standing 1 nautical mile (1.9 km) northeast of Mount Skarshovden in the central Humboldt Mountains, Queen Maud Land. Discovered and plotted from air photos by German Antarctic Expedition, 1938–39. Mapped from air photos and surveys by Norwegian Antarctic Expedition, 1956–60; remapped by Soviet Antarctic Expedition, 1960–61, and named Gora Pervomayskaya.

Mount Flånuten is a mountain 2,725 metres (8,940 ft) high extending as a massif between Livdebotnen Cirque and Vindegghallet Glacier, in the Humboldt Mountains of Queen Maud Land, Antarctica. It was discovered and photographed by the Third German Antarctic Expedition, 1938–39. It was mapped by Norway from air photos and surveys of the Sixth Norwegian Antarctic Expedition, 1956–60, and named Flånuten.

Sandhø Heights is a bare rock heights forming the summit area in the central Conrad Mountains, in Queen Maud Land. Discovered and photographed by the German Antarctic Expedition of 1938-39 and mapped by Norway from air photos and surveys by Norwegian Antarctic Expedition, 1956–60, and named Sandhø.

Sandegga Ridge is a ridge extending south for 5 nautical miles (9 km) from Sandho Heights in the Conrad Mountains of the Orvin Mountains, Queen Maud Land. Discovered and photographed by the German Antarctic Expedition, 1938–39. Mapped by Norway from air photos and surveys by Norwegian Antarctic Expedition, 1956–60, and named Sandegga.

Sagbladet Ridge is a rock ridge at the east side of the mouth of the Austreskorve Glacier, in the Muhlig-Hofmann Mountains of Queen Maud Land. Plotted from surveys and air photos by Norwegian Antarctic Expedition (1956–60) and named Sagbladet.

The Holtedahl Peaks are a group of peaks and ridges lying northward of Steinskaret Gap and forming the northern portion of the Kurze Mountains, in Queen Maud Land, Antarctica. The name "Holtedahlfjella" was applied to the entire extent of the Kurze Mountains on a Norsk Polarinstitutt map of 1966, but the name Kurze has priority, having been given by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39. For the sake of historical continuity, Kurze Mountains has been retained as applied by Ritscher; the name Holtedahl Peaks is recommended for the elevations northward of Steinskaret Gap in these mountains. The name is for Professor Olaf Holtedahl, a noted Norwegian geologist who worked in the South Shetland Islands and the Palmer Archipelago area in 1927–28.

Kal'vets Rock is a rock outcrop lying 2 nautical miles (4 km) west-southwest of the summit of Mount Flånuten on the west side of the Humboldt Mountains, Queen Maud Land, Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, and mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60. It was remapped by the Soviet Antarctic Expedition, 1960–61, and named after Soviet pilot O.A. Kal'vets.
