The Rawson Mountains (86°43′S 154°40′W / 86.717°S 154.667°W / -86.717; -154.667) lie within the Queen Maud Mountains to the southeast of the Ross Ice Shelf in Antarctica. They are a crescent-shaped range of tabular, ice-covered mountains including Fuller Dome, Mount Wyatt and Mount Verlautz, standing southeast of Nilsen Plateau and extending southeast for 18 nautical miles (33 km; 21 mi) to the west side of Scott Glacier.[1]

Discovery and naming

[edit]

The Rawson Mountains were discovered in December 1934 by the Byrd Antarctic Expedition geological party under Quin Blackburn. They were named by Richard E. Byrd for Frederick H. Rawson, American banker and contributor to the Byrd Antarctic Expeditions of 1928-30 and 1933-35.[1]

Location

[edit]

The Rawson Mountains are to the southeast of Nilsen Plateau and south of the head of the Holdsworth Glacier. The Scott Glacier forms to their east and flows north towards the Ross Ice Shelf. The Amundsen Glacier forms to their west and flows northwest towards the Ross Ice Shelf.[2]

Features of the Rawson Mountains, from west to east, include Fuller Dome, Mount Wyatt and Mount Verlautz. To the south of the mountains is the Poulter Glacier, which in turn is north of the isolated Mount Innes-Taylor, Mount Saltonstall, Mount Weaver and Mount Wilbur. To the north of the mountains are a line of mountains west of Scott Glacier including Mount Przywitowski, McNally Peak, Mount Farley, Mount Denauro, Lee Peak, Mount Ruth and Mount Gardiner. These last two stand where Bartlett Glacier and Scott Glacier converge.[2]
