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. The highest peak is Mount Menzies, with a height of 3,228 m (10,591 ft). Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains, together with other scattered peaks, form an arc about 420 km (260 mi) long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.
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.

Named for Hans Wilhelmsson Ahlmann, chairman of the Swedish committee for the NBSAE.
