Gruber Mountains Wikipedia
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.
