Queen Maud Mountains
Template:Short description Template:Infobox mountain
The Queen Maud Mountains (Template:Coord) are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales.Template:Sfn
Exploration and naming
Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.Template:Sfn
Appearance
The Sailing Directions for Antarctica (1960) describes the Queen Maud Range as follows: "From the Beardmore Glacier the horst trends east-southeastward an undetermined distance. The Prince Olaf Mountains stretch from the Beardmore Glacier to the Liv Glacier.Template:Efn Near Template:Coord a large glacier trends southward. Eastward of 175°E. the escarpment is fronted for about 50 miles by high gneissic foothills which are fronted by an expansive piedmont inundating the lower heights. In about Template:Coord the Shackleton Glacier (Wade Glacier), a vast straight-walled glacier about 12 miles wide, extends southward to the polar plateau.Template:Sfn
"At this point the scarp appears broken by a transverse fault which displaces the horst northward to Mount Wade (Mount Bush), a beacon sandstone massif rising to at least 14,000 feet above sea level, dominating the eastern flank of this remarkable valley glacier.Template:Sfn Eastward of Mount Wade stand the Fisher Mountains, which form the western flank of the Liv Glacier.Template:Sfn Bush Mountains, lying just eastward of the mouth of Shackleton Glacier, are a group of ragged foothills rising to a height of 4,000 feet.Template:Sfn
"Viewed from northward the Queen Maud Range presents a vast array of low-lying peaks which increase progressively in height to the southward where, about 15 miles from the shelf ice, stand great tabular mountain masses, 13,000 feet high, having a sharply defined fault-line scarp on the northern side. The northern foothills are dark-colored gneisses and schists with veins of granite and quartz. These foothills show marked glacierization with well-developed cirques and aretes. The high tabular mountains of the horst, are regular and even in outline, presenting broad domes with precipitous fronts to the north showing the granite structure capped by a series of horizontally bedded sandstone with intruded dolerite sills."Template:Sfn

The Queen Maud Mountains are crossed by several major glaciers that flow from the Antarctic Plateau to the Ross Ice Shelf, and divide the mountains.
- The Beardmore Glacier is one of the largest valley glaciers in the world, being Template:Convert long and having a width of Template:Convert.Template:Sfn It descends about Template:ConvertTemplate:Sfn from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range on the eastern side and the Queen Alexandra Range on the western.Template:Sfn
- The Shackleton Glacier is a major glacier, over Template:Convert long and from Template:Convert wide, descending from the Antarctic Plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs.Template:Sfn
- The Liv Glacier is a steep valley glacier, Template:Convert long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and the Duncan Mountains.Template:Sfn
- The Amundsen Glacier is a major Antarctic glacier, about Template:Convert wide and Template:Convert long. It originates on the Antarctic Plateau where it drains the area to the south and west of Nilsen Plateau, then descends through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks.Template:Sfn
- The Scott Glacier is a major glacier, Template:Convert long, that drains the East Antarctic Ice Sheet through the Queen Maud Mountains to the Ross Ice Shelf.Template:Sfn
- The Reedy Glacier is a major glacier, over Template:Convert long and Template:Convert wide, descending from the polar plateau to the Ross Ice Shelf between the Michigan Plateau and Wisconsin Range. It marks the limits of the Queen Maud Mountains on the west and the Horlick Mountains on the east.Template:Sfn
Other glaciers with outlets on the Ross Ice Shelf include
- Canyon Glacier, Giovinco Ice Piedmont, Perez Glacier, Good Glacier, Ramsey Glacier, Erickson Glacier and Kosco Glacier between the Beardmore and Shackleton glaciers.Template:SfnTemplate:Sfn
- Barrett Glacier, Gough Glacier, Le Couteur Glacier, Morris Glacier between the Shackleton and Liv glaciers.Template:Sfn
- Strom Glacier, Axel Heiberg Glacier, Bowman Glacier between the Liv and Amundsen glaciers.Template:Sfn
- Goodale Glacier, Koerwitz Glacier between the Amundsen and Scott glaciers.Template:Sfn
- Leverett Glacier between the Scott and Reedy glaciers.Template:Sfn
These glaciers in turn are generally fed by smaller valley glaciers.
