Ahlmann Ridge, also known as Ahlmannryggen, is a broad, mainly ice-covered ridge, about 110 km (70 mi) long, surmounted by scattered, low peaks. It rises between Schytt Glacier and Jutulstraumen Glacier and extends from Borg Massif northward to Fimbul Ice Shelf in Queen Maud Land. The area was first photographed from aircraft of the Third German Antarctic Expedition (1938–39) and peaks in this vicinity were roughly plotted. The Stein Nunataks and Witte Peaks, named by the German Antarctic Expedition, appear to coincide with the northeast part of the Ahlmann Ridge. The feature was mapped in detail from surveys and air photos by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–1952) and air photos by the Norwegian expedition (1958–59). Named for Hans Wilhelmsson Ahlmann, chairman of the Swedish committee for the NBSAE.
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.
Båkeneset Headland is an ice-covered headland, marked by Båken Nunatak near the seaward end, forming the northwest extremity 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 Norwegian expedition (1958–59), and named "Båkeneset".
Botnfjellet Mountain is a mountain, 2,750 metres (9,020 ft) high, forming the northeast and east walls of Livdebotnen Cirque in the Humboldt Mountains of Queen Maud Land. It was discovered and photographed by the Third German Antarctic Expedition, 1937–39. It was mapped by Norway from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named "Botnfjellet".

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 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.
Dekefjellet Mountain is an elongated mountain, about 3 nautical miles (6 km) long and surmounted by Kamskaya Peak, standing 1.5 nautical miles (3 km) west of Skavlrimen Ridge in the Weyprecht Mountains, Queen Maud Land. The feature is partly rock and partly covered with snow. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39. The mountain was replotted from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named Dekefjellet.
Kråsen Crevasse Field is a crevasse field about 15 nautical miles (30 km) long in the lower part of Jutulstraumen Glacier, in Queen Maud Land, Antarctica. 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 Kråsen.
Storsåtklubben Ridge is a ridge, 3 nautical miles (5.6 km) long, located 5 nautical miles (9.3 km) northeast of Mount Hansen in the Mittlere Petermann Range, in the Wohlthat Mountains of Queen Maud Land. It was discovered and plotted from air photos by the German Antarctic Expedition of 1938-39 and replotted from air photos and surveys by the Norwegian Antarctic Expedition in 1956–60, and named Storsåtklubben'.
Trollkjelen Crevasse Field is a crevasse field about 12 nautical miles (22 km) long in the Fimbul Ice Shelf, lying immediately off the northeast side of Trollkjelneset Headland in Queen Maud Land. Mapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–52) and air photos by the Norwegian expedition (1958–59) and named Trollkjelen.
Fred Cirque is a large cirque in the west side of Roots Heights, in the Sverdrup Mountains of Queen Maud Land, Antarctica. It was photographed from the air by the Third German Antarctic Expedition (1938–39). It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (NBSAE) (1949–52) and from air photos by the Norwegian expedition (1958–59). It was named for Ernest Frederick Roots, chief geologist with the NBSAE.
Mirazh Mountain is a peak rising to 1,485 metres (4,870 ft) on the north-central part of Steinmulen Shoulder in the Gruber Mountains of Queen Maud Land, Antarctica.

The mountain was remapped by the Soviet Antarctic Expedition in 1960–61, and named "Gora Mirazh".
Helle Slope is a large ice piedmont along the coast of Queen Maud Land, Antarctica, lying east of Jutulstraumen Glacier and north of the Mühlig-Hofmann Mountains. It was photographed from the air by the Third German Antarctic Expedition (1938–39); it was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and from air photos by the Norwegian expedition (1958–59), and was named for Sigurd Helle, leader of the 1957 Norwegian expedition to Queen Maud Land.
Steinmulen Shoulder is a rock shoulder extending north from Mount Zimmermann in the Gruber Mountains of the Wohlthat Mountains, Queen Maud Land.

Sjøbotnen Cirque is the prominent cirque in the north face of the main massif of the Gruber Mountains, situated immediately east of Mount Zimmermann, in the Wohlthat Mountains of Queen Maud Land. It was discovered and plotted from air photos by the German Antarctic Expedition of 1938-39, and replotted from air photos and surveys by the Norwegian Antarctic Expedition, 1956–60, and named Sjøbotnen because the inner part of the feature is occupied by a sizable lake.
Søråsen Ridge is a broad, snow-covered ridge that separates the Quar and Ekström Ice shelves, on the coast of Queen Maud Land. The feature was first mapped and named Søråsen by the Norwegian-British-Swedish Antarctic Expedition, 1949-52.
Kamskaya Peak is, at 2,690 metres (8,830 ft), the highest peak of Dekefjellet Mountain in the Weyprecht Mountains of Queen Maud Land, Antarctica.
