Roald Engelbregt Gravning Amundsen (] ; 16 July 1872 – c. 18 June 1928) was a Norwegian explorer of polar regions.
 As the leader of the Antarctic expedition of 1910–12, which was the first to reach the South Pole, on 14 December 1911, he was a key expedition leader during the Heroic Age of Antarctic Exploration.
 In 1926, he was the first expedition leader for the air expedition to the North Pole, making him the first person, without dispute, to reach both poles.
 He is also known as having the first expedition to traverse the Northwest Passage (1903–06) in the Arctic.
Ragged Peaks ( ) is a prominent group of peaks on the eastern side of Amundsen Bay in a line running almost north-south.
 The peaks, extending 8 nautical miles (15 km), contain several spires and the ridge connecting the peaks is much serrated.
 There are five peaks over 915 meters.
 They were sighted in October 1956 by the ANARE (Australian National Antarctic Research Expeditions) Amundsen Bay party led by P.W. Crohn.
 The descriptive name was given by the Antarctic Names Committee of Australia (ANCA).
Mount Hassel ( ) is a rock peak 2,390 m high, the northeasternmost summit of the massif at the head of Amundsen Glacier, in the Queen Maud Mountains of Antarctica.
 In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen.
 Amundsen named one of them for Sverre Hassel, a member of the party.
 The peak described was mapped by the United States Geological Survey from surveys and U.S. Navy aerial photography, 1960–64.
 For the sake of historical continuity and to commemorate the Norwegian exploration in this area, the Advisory Committee on Antarctic Names has selected this feature to be designated Mount Hassel.
 Other peaks in the massif have also been named for members of Amundsen's South Pole Party.
Albert Paddock Crary (July 25, 1911 – October 29, 1987), was a pioneer polar geophysicist and glaciologist.
 He was the first person to have stepped foot on both the North and South Poles, having made it to the North Pole on May 3, 1952 (with Joseph O. Fletcher and William P. Benedict) and then to the South Pole on February 12, 1961 as the leader of a team of eight.
 The South Pole expedition set out from McMurdo Station on December 10, 1960, using three Snowcats with trailers.
 Crary was the seventh expedition leader to arrive at the South Pole by surface transportation (the six others before him were—in sequence—Amundsen, Scott, Hillary, Fuchs, a Russian expedition in 1959/60 from Vostok base, and Antero Havola).
 He was widely admired for his intellect, wit, skills and as a great administrator for polar research expeditions.
Mount Wisting ( ) is a rock peak (2,580 m), the northwesternmost summit of the massif at the head of Amundsen Glacier in the Queen Maud Mountains.
 In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen.
 Amundsen named one of them for Oscar Wisting, a member of the party.
 The peak described was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy aerial photography, 1960-64.
 For the sake of historical continuity and to commemorate the Norwegian exploration in this area, the Advisory Committee on Antarctic Names (US-ACAN) has selected this feature to be designated Mount Wisting.
 Other peaks in the massif have been named for members of Amundsen's South Pole Party.
The South Pole Traverse, also called the McMurdo–South Pole Highway, is an approximately 995 mi compacted snow road in Antarctica that links the United States's McMurdo Station on the coast to the Amundsen–Scott South Pole Station.
 It was constructed by leveling snow and filling in crevasses, but is not paved; flags mark its route.
Amundsen Bay, also known as Ice Bay, is a long embayment 24 mi wide, close west of the Tula Mountains in Enderby Land, Antarctica.
 The bay was seen as a large pack-filled recession in the coastline by Sir Douglas Mawson on January 14, 1930.
 Seen by Captain Hjalmar Riiser-Larsen in charge of a Norwegian expedition during an airplane flight on January 15 and subsequently mapped nearer its true position by the Norwegians.
 The bay was mapped in detail by an Australian National Antarctic Research Expeditions party landed by aircraft in 1956 and another landed by launch from "Thala Dan" in February 1958.
 It was named by Mawson after Roald Amundsen, the Norwegian explorer who was first to reach the South Pole.
Between December 1911 and January 1912, both Roald Amundsen (leading his South Pole expedition) and Robert Falcon Scott (leading the Terra Nova expedition) reached the South Pole within a month of each other.
 But while Scott and his four companions died on the return journey, Amundsen's party managed to reach the pole first and subsequently return to their base camp at Framheim without loss of life, suggesting that they were better prepared for the expedition.
 The contrasting fates of the two teams seeking the same prize at the same time invites comparison.
Mount Bjaaland ( ) is a rock peak (2,675 m), the southeasternmost summit of the massif at the head of Amundsen Glacier, in the Queen Maud Mountains.
 In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen.
 Amundsen named one of them for Olav Bjaaland, a member of the party.
 The peak described was mapped by United States Geological Survey (USGS) from surveys and U.S. Navy aerial photography, 1960-64.
 For the sake of historical continuity and to commemorate the Norwegian exploration in this area, the Advisory Committee on Antarctic Names (US-ACAN) has selected this feature to be designated Mount Bjaaland.
 Other peaks in the massif have been named for members of Amundsen's South Pole Party.
Roald Amundsen's South Pole Journey (Norwegian: "Roald Amundsens sydpolsferd" ) is a Norwegian documentary film that features Roald Amundsen's original footage from his South Pole expedition from 1910 to 1912.
 The film was seen for the first time in 1912 and it was used by Amundsen for his traveling lectures.
