The Beardmore Glacier in Antarctica 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). [1] It descends about 2,200 m (7,200 ft) [1] from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. [2]

The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the South Pole despite its steep upward incline.

The glacier was discovered and climbed by Ernest Shackleton during his Nimrod Expedition of 1908. Although Shackleton turned back at latitude 88° 23' S, just 97.5 nautical miles (180.6 km; 112.2 mi) from the South Pole, he established the first proven route towards the pole and, in doing so, became the first person to set foot upon the polar plateau. In 1911–1912, Captain Scott and his Terra Nova Expedition team reached the South Pole by similarly climbing the Beardmore. However, they reached the pole a month after Roald Amundsen and his team, who had chosen a route up the previously unknown Axel Heiberg Glacier. It was on the way back to the Nova expedition's base camp after they left the South Pole that Edgar Evans, one of the members of Scott's chosen team to go to on the final trek to the South Pole, died around the foot of Beardmore Glacier on February 17, 1912.

Beardmore Glacier was named by Shackleton after Sir William Beardmore, a Scottish industrialist and expedition sponsor born in 1856.

In 2016 the first beetle fossils, in the form of wing-cases (elytra) of Ball's Antarctic tundra beetle, 14 to 20 million years old, were found on the glacier. [3] [4]

Vinson Massif massif containing the highest peak in Antarctica

Vinson Massif is a large mountain massif in Antarctica that is 21 km (13 mi) long and 13 km (8.1 mi) wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about 1,200 kilometres (750 mi) from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities.

Transantarctic Mountains mountain range in Antarctica

The Transantarctic Mountains comprise a mountain range of uplifted rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges.

The Nimrod Glacier is a major glacier about 135 km (85 mi) long, flowing from the polar plateau in a northerly direction through the Transantarctic Mountains between the Geologists and Miller Ranges, then northeasterly between the Churchill Mountains and Queen Elizabeth Range, and finally spilling into Shackleton Inlet and the Ross Ice Shelf between Capes Wilson and Lyttelton.

The Reedy Glacier is a major glacier in Antarctica, over 160 km (100 mi) long and from 10 to 19 km wide, descending from the polar plateau to the Ross Ice Shelf between the Michigan Plateau and Wisconsin Range, and marking the limits of the Queen Maud Mountains on the west and the Horlick Mountains on the east.

Axel Heiberg Glacier glacier in Antarctica

The Axel Heiberg Glacier in Antarctica is a valley glacier, 30 nmi (35 mi) long, descending from the high elevations of the Antarctic Plateau into the Ross Ice Shelf between the Herbert Range and Mount Don Pedro Christophersen in the Queen Maud Mountains.

Leverett Glacier in Antarctica is about 50 nautical miles (90 km) long and 3 to 4 nautical miles wide, draining northward from the Watson Escarpment, between California Plateau and Stanford Plateau, and then trending west-northwest between the Tapley Mountains and Harold Byrd Mountains to terminate at the head of the Ross Ice Shelf close east of Scott Glacier. It was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by him for Frank Leverett, an eminent geologist at the University of Michigan and an authority on the glacial geology of the central United States.

Wally Herbert British polar explorer

Sir Walter William "Wally" Herbert was a British polar explorer, writer and artist. In 1969 he became the first man fully recognized for walking to the North Pole, on the 60th anniversary of Robert Peary's famous, but disputed, expedition. He was described by Sir Ranulph Fiennes as "the greatest polar explorer of our time".

<i>Nimrod</i> Expedition first of three Antarctic expeditions led by Ernest Shackleton

The NimrodExpedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three expeditions to the Antarctic led by Ernest Shackleton. Its main target, among a range of geographical and scientific objectives, was to be first to the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just 97.5 nautical miles from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South Magnetic Pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano.

<i>Terra Nova</i> Expedition Research expedition to the South Pole

The Terra NovaExpedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. It was led by Robert Falcon Scott and had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the Discovery expedition to the Antarctic from 1901 to 1904. He also wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that the Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's entire party died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later.

Shackleton Coast portion of the coast along the west side of the Ross Ice Shelf, Antarctica

Shackleton Coast is that portion of the coast along the west side of the Ross Ice Shelf between Cape Selborne and Airdrop Peak at the east side of Beardmore Glacier in Antarctica. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Sir Ernest Shackleton. He accompanied Scott on the southern journey during the Discovery expedition (1901–04) and subsequently led three Antarctic expeditions. On the British Antarctic Expedition (1907–09), Shackleton discovered the area beyond Shackleton Inlet to the Beardmore Glacier, and was the first to find a practicable route to the South Pole. Lack of food stopped him 97 miles (180 km) from his goal.

Mullins Valley is a four mile long valley located at 5,400 ft elevation in the McMurdo Dry Valleys. It is one of the few dry valleys in the world to contain rock glaciers. US Antarctic Program (USAP) research has dated the subsurface ice in Mullins Valley at 4 million years old making it among the oldest ice on earth. United States Antarctic Program (USAP) research has also shown the rock glaciers in the valley to be analogous to the Arsia Mons region on Mars. Named for Jerry L.

His was responsible for Antarctic field research in the Transantarctic Mountains, McMurdo Dry Valleys, Shackleton Mountains, Beardmore Mountains, Antarctic Peninsula, Mount Siple, Amundsen-Scott South Pole station and at deep field research locations in West Antarctica. His program conducted research in the disciplines of global positioning systems, geodesy, crustal motion, glacial geophysics, airborne geospatial systems, airborne geophysics, seismology, light radar (lidar), topographic mapping and he managed the USGS South Pole winter-over program from 1989 to 1994. He was appointed by the National Academy of Sciences, Polar Research Board as a US delegate to the Scientific Committee on Antarctic Research Geosciences Standing Scientific Group from 1995–July 2012 and was appointed as a member of the Advisory Committee on Antarctic Names in 1994. Mullins Valley appears in the Antarctic research literature, on the maps from the British expedition of Captain Scott and in aerial photographs from the United States expedition Operation Highjump by Admiral Byrd.
