The Scott Glacier (85°45′S 153°0′W / 85.750°S 153.000°W) 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.[1] The Scott Glacier is one of a series of major glaciers flowing across the Transantarctic Mountains, with the Amundsen Glacier to the west and the Leverett and Reedy glaciers to the east.

Geography
editThe Scott Glacier originates on the Antarctic Plateau in the vicinity of D'Angelo Bluff and Mount Howe, and descends between the Nilsen Plateau and the mountains of the Watson Escarpment to enter Ross Ice Shelf just west of the Tapley Mountains.[1] The Tapley Mountains, Watson Escarpment, Mount Blackburn, and the La Gorce Mountains bound the Scott Glacier on its eastern margin, while the Karo Hills, Hays Mountains, Faulkner Escarpment, and Rawson Mountains define the western edge of the Scott's drainage.
According to Sailing Directions for Antarctica (1960),"Eastward of the Amundsen Glacier the foothills are more nearly submerged beneath snow and ice, and show greater evidence of glacierization than those in the vicinity of the Axel Heiberg and Liv Glaciers. About 15 miles eastward of the Amundsen Glacier is the Robert Scott Glacier (Thorne Glacier), from 5 to 15 miles wide, trending in a north-south direction about 90 miles. Thorvald Nilsen Mountains (Mount Thorvald Nilsen) (86°W' S.,158°00' W.), a mountain massif of the Queen Maud Range, rise to elevations of about 13,000 feet and lie between the upper parts of the Scott and Amundsen Glaciers.[2]
The Will Hays Mountains (85°57' S., 155°20' W.) also in the Queen Maud Range, surmount the divide between the lower ends of these two glaciers. Mount Thorne rises to 6,000 feet in the Will Hays Mountains. Mount Weaver (86°57' S, 152°20' W.), about 10,000 feet high, marks the southern portal of the glacier at the polar plateau. Blackburn in 1934, found at Mount Weaver extensive coal beds and fossil tree section up to 18 inches in diameter.[2]
The eastern wall of the Robert Scott Glacier is marked by a series of isolated flat-topped mountains between which tributary glaciers drain from the polar plateau into the Thorne Valley. The eastern portal of the Robert Scott Glacier is marked by a detached land mass, about 30 miles long in a southeast-northwest direction. Southward of this massif is Albanus Glacier (Phillips Glacier), which flows westward and merges with the lower heights of Robert Scott Glacier. The Albanus Glacier and the Leverett Glacier bifurcate at the eastern extremity of the detached land mass in about 85°48' S., 146° W.[2]
History
editScott Glacier was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould.[1] Scott Glacier was originally called Thorne Glacier.[3] The Scott Glacier was named by the Advisory Committee on Antarctic Names (US-ACAN) after early Antarctic explorer Robert Falcon Scott, who never saw the Scott Glacier but rather ascended the Beardmore Glacier to the west en route to the South Pole in 1911–12. It was first ski traversed in January 1990 by Martyn Williams (Canada, the leader and guide) and Jerry Corr (USA) traveling from the South Pole to the Ross Ice Shelf and then by Mike McDowell (Australia) in 1992, on a ski traverse from the South Pole to the coast. Thus Williams and Corr were the first people to traverse Antarctica under human power as described in the book The Snotsicle Traverse by Jerry Corr.
Course
editThe Scott Glacier forms on the Polar Plateau and flows north between Mount Wilbur and the Davis Hills. The Poulter Glacier enters from the left (west) to the north of Mount Innes-Taylor.[4] The Klein Glacier enters from the right (east) to the north of the David Hills.[5] The Robison Glacier enters from the right to the south of Mount Bowlin and the VanReeth Glacier enters from the right to the north of Mount Bowlin. The Scott Glacier flows past the Watson Escarpment to the east, from which the Howe Glacier and Griffith Glacier join it from the right.[5]
To the north of Mount Ruth, to the west of the Scott Glacier, the Bartlett Glacier joins from the left. Tributaries of the Bartlett Glacier include the Holdsworth Glacier and the Souchez Glacier.[4] Further north, the Scott Glacier flows past the Tapley Mountains to the east, from which it receives the Albanus Glacier and the Roe Glacier. From the Queen Maud Mountains to the west it receives the Vaughan Glacier. The Koerwitz Glacier flows beside the Scott Glacier then pulls away at Mount Salisbury in the Karo Hills.[6]
Head
edit
The head of the Scott Glacier forms between the D'Angelo Bluff and Mount McIntyre to the west and Mount Howe to the east. The glacier flows north past Mount Early and Sunny Ridge to the west.[7]

The bluff stands at the west side of Scott Glacier, near the head, 13 nautical miles (24 km; 15 mi) south of Mount Early. Discovered by the Byrd Antarctic Expedition geological party led by Quin Blackburn, in December 1934. The bluff was visited December 5, 1962 by a geological party of the Ohio State University Institute of Polar Studies, led by George Doumani.
