The Gruber Mountains (German: Otto-von-Gruber-Gebirge) 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. [1]
Several features within the Gruber Mountain range have been charted and named by expeditions and survey groups.
Mount Bastei ( 71°22′S13°32′E / 71.367°S 13.533°E ) is a prominent buttress-type mountain 2,460 metres (8,070 ft) high, 3.7 km (2.3 mi) west of Mount Mentzel. It was discovered and named Bastei, meaning bastion, by the German Antarctic Expedition, 1938–39, under Ritscher. [2]
Ufsekammen Ridge ( 71°24′S13°14′E / 71.400°S 13.233°E ) is an arc-shaped rock ridge, 4.8 km (3.0 mi) long, between Mount Schicht and Ufsebrotet Bluff. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39. The Norwegian Antarctic Expedition of 1956–60 replotted it from air photos and surveys and named it Ufsekammen (the bluff ridge). [3]
A 500 ha site in the mountains, in the vicinity of Lake Untersee, has been designated an Important Bird Area (IBA) by BirdLife International because it supports about 10,000 breeding snow petrels, estimated in 1983. [4]
New Swabia was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, Schwabenland, itself named after the German region of Swabia.
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.

Wohlthat, who as economist and fiscal officer dealt with the organization of the expedition.
The Humboldt Mountains are a group of mountains immediately west of the Petermann Ranges, forming the westernmost portion of the Wohlthat Mountains in Queen Maud Land, Antarctica.
Ufsebrotet Bluff is a steep bluff located 2 miles (3.2 km) south of Mount Zimmermann in the central Gruber Mountains of the Wohlthat Mountains, Queen Maud Land. Discovered and plotted from air photos by German Antarctic Expedition, 1938–39. Replotted from air photos and surveys by Norwegian Antarctic Expedition, 1956–60, and named Ufsebrotet.
Mount Zuckerhut is a peak standing 3.2 km (2.0 mi) southeast of Ritscher Peak in the Gruber Mountains of Queen Maud Land. Discovered and given the descriptive name Zuckerhut (sugarloaf) by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher.
Sandeggtind Peak is a 3,055 metres (10,023 ft) tall peak, standing 1.5 km (1 mi) south of Sandho Heights on Sandegga Ridge in the Conrad Mountains, Queen Maud Land. It was discovered and photographed by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher. It was mapped by Norway from air photos and surveys by NorAE, 1956–60, and named Sandeggtind.
The Mühlig-Hofmann Mountains is a major group of associated mountain features extending east to west for 100 km (62 mi) between the Gjelsvik Mountains and the Orvin Mountains in Queen Maud Land, East Antarctica. With its summit at 3,148 metres (10,328 ft), the massive Jøkulkyrkja Mountain forms the highest point in the Mühlig-Hofmann Mountains.
Ritscher Peak is a 2,790-metre (9,150 ft) peak located 11 kilometres (7 mi) west-southwest of Mount Mentzel in the Gruber Mountains of Queen Maud Land, Antarctica. This peak was discovered and mapped by the Third German Antarctic Expedition of 1938–39 and was named for Capt. Alfred Ritscher, leader of the expedition.
Mount Neustruyev is a peak in East Antarctica, 2,900 m, standing 5 mi NNE of Gneiskopf Peak in Südliche Petermann Range, Wohlthat Mountains, Queen Maud Land.
Anuchin Glacier is a glacier draining southward to Lake Unter-See in the northern part of the Gruber Mountains, Queen Maud Land. It was discovered, and plotted from air photos, by the Third German Antarctic Expedition, 1938–39. It was mapped from air photos and from surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and remapped by the Soviet Antarctic Expedition, 1960–61, and named after Dmitry Nikolayevich Anuchin, Soviet geographer.
Asimutbreen Glacier is a small, steep tributary glacier to Vangengeym Glacier, descending southeast and then northeast between Solhogdene Heights and Skuggekammen Ridge, in the eastern Gruber Mountains of the Wohlthat Mountains, Queen Maud Land. 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.
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.
Mount Schicht is a prominent mountain with several summits, rising 4 nautical miles (7 km) west-southwest of Ritscher Peak in the Gruber Mountains of Queen Maud Land. The feature was discovered by the German Antarctic Expedition under Ritscher, 1938–39, and named Schichtberge because of its appearance.
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.

Discovered and plotted from air photos by German Antarctic Expedition, 1938–39. Replotted from air photos and surveys by Norwegian Antarctic Expedition, 1956–60, and named Skuggekammen.
Solhogdene Heights is the heights 1 nautical mile (1.9 km) east of Mount Mentzel, overlooking the north side of Asimutbreen Glacier in the eastern Gruber Mountains of the Wohlthat Mountains, Queen Maud Land. Discovered and plotted from air photos by German Antarctic Expedition, 1938–39. Replotted from air photos and surveys by Norwegian Antarctic Expedition, 1956–60, and named Solhogdene.
