Poor surfaces and snowfall made the going heavy. "A tired animal makes a tired man, I find," Scott wrote, "and none of us are very bright now after the day's march, though we have had ample sleep of late." 
A 1966 map of the Nilsen Plateau and surrounding area, from aerial photographs taken 1960-1964 by the USGS. The nearby Amundsen Glacier was discovered and named on Byrd's 1929 flight. The Axel Heiberg Glacier is to the north-west, on a separate map. 
The going was still through fog and blizzard. The glimpse of a dark mass to the E.S.E. was the discovery of what was later called the Nilsen Plateau after the Fram's captain. Another sighting, of what Amundsen afterwards described in a letter to Helland-Hansen as "a gloriously beautiful mountain, in fact two, in the distant, wonderfully lovely land around the Pole which I have given you" , proved -- albeit only many years later -- to have been an illusion, sparked not only by the deceptive play of light in that area but Amundsen's own disinterest in geographic surveys.

 See Roland Huntford, Scott and Amundsen (New York : Putnam, 1980, c1979), p.454. Amundsen made only sketchy drawings and took few photographs, but it should be pointed out that his dead-reckoning position of the Butcher's Shop, for example, proved later to have been within a mile of its true bearing. His navigational precision is not in question, only his lack of interest in "minor" details.
