Nilsen Plateau ( 86°20′S 158°0′W  /  86.333°S 158.000°W  / -86.333; -158.000 ) is a rugged, ice-covered plateau in Antarctica. When including Fram Mesa, the plateau is about 30 nautical miles (56 km; 35 mi) long and 1 to 12 nautical miles (1.9 to 22.2 km; 1.2 to 13.8 mi) wide, rising to 3,940 metres (12,930 ft) 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 .
