The day "was sour as vinegar," wrote Bjaaland, "-47.5 deg. with N.W. wind right in the phiz; delightful. The dogs are suffering horribly in the cold; they are miserable, in agony with frostbitten paws. Adam and Lazarus froze to death when they lay down." 
The breeze dropped in the afternoon, and the going improved -- Amundsen pulled along on ski behind Wisting's sledge -- so that they did 31 nautical miles by mid-afternoon. The temperature in the evening was -35° (-31° F).
