Gruber Mountains

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 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.
