Nilsen Plateau (-86.3333°N -158°W) is a rugged, ice-covered plateau in Antarctica. When including Fram Mesa, the plateau is about long and 1to wide, rising to high between the upper reaches of the Amundsen and Scott glaciers, in the Queen Maud Mountains. Discovered in November 1911 by the Norwegian expedition under Roald Amundsen, and named by him for Captain Thorvald Nilsen, commander of the ship Fram.
The Nilsen Plateau lies to the east of the upper Amundsen Glacier and north of the Rawson Mountains. The Bartlett Glacier forms on its southeast side.The Faulkner Escarpment defines its east side.The Hays Mountains are to the north, separated from the plateau by the Cappellari Glacier.Features just to the south of these two glaciers include Mount Dort, Mount Clough and Simmonds Peak.South of these are Gregory Ridge, Mount Bowser.
The Nilsen Plateau proper includes Beck Peak, Mount Stubberud, Mount Sundbeck, Moraine Canyon and Fram Mesa.Further south again are Olsen Crags, Hansen Spur (south of Blackwall Glacier) and Crown Mountain.To the south of Epler Glacier are Lindstrom Peak, Mount Kristensen, Kutschin Peak and Mount Kendrick in the east.
-86.0833°N -216°W. A peak, high, on the east flank of Amundsen Glacier, standing northwest of Mount Stubberud on the ridge descending from northern Nilsen Plateau. This peak appears to have been first mapped from air and ground photos taken by the Byrd Antarctic Expedition, 1928-30. It was mapped in greater detail by the United States Geological Survey (USGS) from surveys andUnited States Navy air photos, 1960-64. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) for A. Beck, a crew member on the Fram on Amundsen's Norwegian expedition of 1910-12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount A. Beck," a name applied for an unidentifiable mountain in the general area.
-86.1167°N -203°W. A mountain, high, standing southeast of Beck Peak on a ridge from the north side of Nilsen Plateau. Mapped by USGS from surveys andUnited States Navy air photos, 1960-64.Named by US-ACAN for Jorgen Stubberud, carpenter on the ship From and member of the land party at Framheim on Amundsen's expedition of 1910-12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount J. Stubberud," a name applied for an unidentifiable mountain in the general area.
-86.1667°N -186°W. A peak, high, standing southeast of Mount Stubberud on a ridge from the north side of Nilsen Plateau.Mapped by USGS from the surveys andUnited States Navy air photos, 1960-64.Named by US-ACAN for Knut Sundbeck, engineer of the ship Fram on Amundsen's Norwegian expedition of 1910-12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount K. Sundbeck," a name applied for an unidentifiable mountain in the general area.
-86.2°N -208°W. Rugged crags surmounting a small but conspicuous mountain block that projects into the east side of Amundsen Glacier just north of Epler Glacier, in the Queen Maud Mountains. Mapped by USGS from surveys andUnited States Navy air photos, 1960-64. Named by US-ACAN for Karinius Olsen, cook on the From, the ship of Amundsen's Norwegian expedition of 1910-12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount K. Olsen," a name applied for an unidentifiable mountain in the general area.

Mapped by USGS from surveys andUnited States Navy air photos, 1960-64. Named by US-ACAN for Ludvig Hansen, a member of the sea party aboard the Fram on Amundsen's Norwegian expedition of 1910-12. This naming preserves the spirit of Amundsen's 1911 commemoration of "Mount L. Hansen," a name applied for an unidentified mountain in the general area.
-86.3°N -203°W. A mountain, high, surmounting the west side of Nilsen Plateau, east-northeast of Mount Kristensen.Mapped by USGS from surveys andUnited States Navy air photos, 1960-64.Named by US-ACAN to describe the appearance of the summit, a somewhat circular rock band contrasting with the ice surface of Nilsen Plateau.
-86.15°N -187°W. A canyon with very steep rock walls, long, indenting northern Nilsen Plateau just west of Fram Mesa. Mapped by USGS from surveys andUnited States Navy air photos, 1960-64. So named by US-ACAN because the canyon floor is completely covered by glacial moraine.
-86.05°N -203°W. A narrow rock ridge descending westward from northern Fram Mesa and terminating at the east side of Amundsen Glacier. Mapped by USGS from surveys andUnited States Navy air photos, 1960-64. Named by US-ACAN for Lt. Cdr. N.B. Gregory, pilot on photographic flights duringUnited States Navy OpDFrz 1965.
-86.1333°N -184°W. A high, ice-capped mesa, long and 1to wide, that forms the northeast portion of Nilsen Plateau. The feature may have been seen by Amundsen in 1911, and it was observed and partially mapped by the Byrd Antarctic Expedition of 1928-30 and 1933-35. It was mapped in detail by USGS from surveys andUnited States Navy air photos, 1960-64. Named by US-AC AN after the Fram, the ship used by Amundsen's expedition of 1910-12.
-86.2°N -156°W. An ice-covered escarpment, long and over high, trending in a north–south direction and forming the east edge of Nilsen Plateau and Fram Mesa.

Lindstrøm, cook for the land party at Framheim on Amundsen's expedition of 1910-12. This naming preserves the spirit of Amundsen's commemoration of "Mount A. Lindstrøm," a name applied in 1911 for an unidentifiable mountain in the general area.
-86.3333°N -199°W. A mountain, high, standing on the west side of Nilsen Plateau southeast of Lindstrøm Peak. Named by US-ACAN in 1967 for H. Kristensen, an engineer on the ship From of Amundsen's Norwegian expedition of 1910-12. This naming preserves Amundsen's commemoration of "Mount H.

The high and precipitous rock cliffs just northward of Kutschin Peak on the west side of Nilsen Plateau.The name was proposed by William Long, geologist with a USARP field party that visited the area in the 1963-64 season. The name is descriptive of the sound made by the wind here; standing in the quiet, windless valley below, a roaring noise like an approaching train can be heard high up on the cliffs.
