Location of Queen Maud mountains in Antarctica

The Queen Maud Mountains (86°00′S 160°00′W / 86.000°S 160.000°W / -86.000; -160.000) 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.[2]

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.[2]

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.[lower-alpha 1] Near 84°S 175°E / 84°S 175°E / -84; 175 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 84°30′S 175°00′W / 84.500°S 175.000°W / -84.500; -175.000 the Shackleton Glacier (Wade Glacier), a vast straight-walled glacier about 12 miles wide, extends southward to the polar plateau.[4]

"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.[4] Eastward of Mount Wade stand the Fisher Mountains, which form the western flank of the Liv Glacier.[5] 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.[6]

"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."[6]

Glaciers

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 200 km (125 mi) long and having a width of 40 km (25 mi).[7] It descends about 7,200 feet (2,200 m)[7] 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.[8]
  • The Shackleton Glacier is a major glacier, over 60 nautical miles (110 km; 69 mi) long and from 5 to 10 nautical miles (9.3 to 18.5 km; 5.8 to 11.5 mi) 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.[9]
  • The Liv Glacier is a steep valley glacier, 40 nautical miles (74 km; 46 mi) 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.[10]
  • The Amundsen Glacier is a major Antarctic glacier, about 4 to 6 nautical miles (7.4 to 11.1 km; 4.6 to 6.9 mi) wide and 80 nautical miles (150 km; 92 mi) 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.[11]
  • The Scott Glacier is a major glacier, 120 nautical miles (220 km; 140 mi) long, that drains the East Antarctic Ice Sheet through the Queen Maud Mountains to the Ross Ice Shelf.[12]
  • The Reedy Glacier is a major glacier, over 100 nautical miles (190 km; 120 mi) long and 6 to 12 nautical miles (11 to 22 km; 6.9 to 13.8 mi) 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.[13]

Other glaciers with outlets on the Ross Ice Shelf include

These glaciers in turn are generally fed by smaller valley glaciers.

Somewhat arcuate, the escarpment is nearly 100 nautical miles (190 km; 120 mi) long, rises 3,550 metres (11,650 ft) above sea level, and 1,000 to 1,500 metres (3,300 to 4,900 ft) above the adjacent terrain.[39]
  • Gothic Mountains, a group of mountains, 20 nautical miles (37 km; 23 mi) long, located west of Watson Escarpment and bounded by Scott Glacier, Albanus Glacier, and Griffith Glacier.[40]
  • La Gorce Mountains, a group of mountains, 20 nautical miles (37 km; 23 mi) long, standing between the tributary Robison Glacier and Klein Glacier at the east side of the upper reaches of the Scott Glacier.[41]

  • Harold Byrd Mountains, a group of exposed mountains and nunataks which extend in an east–west direction between the lower part of Leverett Glacier and the head of the Ross Ice Shelf.[43]
  • Bender Mountains, a small group of mountains 4 nautical miles (7.4 km; 4.6 mi) southwest of the Berry Peaks, between the southeast edge of the Ross Ice Shelf and the Watson Escarpment.[44]

Other features

  • The Quartz Hills is an arcuate cluster of largely ice-free hills and peaks found immediately south of Colorado Glacier along the west side of Reedy Glacier.[33]
  • The Caloplaca Hills are a distinctive group of rock hills including Mount Carmer and Heathcock Peak, lying east of the Watson Escarpment on the west side of Reedy Glacier.[45]
  • Titan Dome is a large ice dome on the polar plateau, trending east–west and rising to 3,100 metres (10,200 ft) between the Queen Maud Mountains and the South Pole. The dome was first crossed by the sledge parties of Shackleton, Amundsen, and Scott on their journeys toward the South Pole, and was described as a major snow ridge. It was delineated by the SPRI-NFS-TUD airborne radio echo sounding program, 1967–79, and named after the Cambridge University (U.K.) Titan computer, which was used to process all the early radio echo sounding data for this part of Antarctica.[46]
