Northwestern features


Beck Peak

. A peak, high, on the east flank of Amundsen Glacier, standing northwest of Mount Stubberud on the ridge descending from northern Nilsen Plateau.

Mount Stubberud

. 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.

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.


Olsen Crags

. 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.

. A spur, long, descending from the northwest side of Nilsen Plateau and terminating at the edge of Amundsen Glacier just east of Olsen Crags. 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.


Crown Mountain

. 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.


Fram Mesa and surroundings


Moraine Canyon

. 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.


Gregory Ridge

. 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.


Fram Mesa

. A high, ice-capped mesa, long and 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.


Faulkner Escarpment

. 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. Discovered in December 1934 by the Byrd Antarctic Expedition geological party under Quin Blackburn, and named by Byrd for Charles J. Faulkner, Jr., chief counsel of Armour and Co. of Chicago, contributors to the expedition.


Mount Bowser

. A prominent peak, high, standing south of Mount Astor at the north end of Fram Mesa. Mapped by USGS from surveys andUnited States Navy air photos, 1960-64. Named by US-ACAN for Carl J. Bowser, geologist at McMurdo Station, 1965-66 and 1966-67 seasons.


Southern features


Lindstrøm Peak

. A peak, high, standing northwest of Mount Kristensen on the west side of Nilsen Plateau. Named by US-ACAN for Adolf H. 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.


Mount Kristensen

. 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. Kristensen," a name applied in 1911 for an unidentifiable mountain in the general area.


Roaring Cliffs

. 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.


Kutschin Peak

. A prominent peak high, on the west slope of the Nilsen Plateau, standing south of Mount Kristensen, at the east side of Amundsen Glacier. Named by US-ACAN for A. Kutschin, a member of the sea party of Amundsen's Norwegian expedition of 1910–12.


Crack Bluff

. A bluff southeast of Kutschin Peak on the west side of Nilsen Plateau. The bluff rises to and has an extensive area of exposed rock. The name was proposed by Edmund Stump of the USARP Ohio State University field party which geologically mapped the bluff on Dec. 27, 1970. It is descriptive of the peculiar subhorizontal crack containing breccia fragments exposed on the steep southwest face.


Mount Kendrick

. A massive ice-covered mountain, high, surmounting the east side of the Nilsen Plateau at the head of
