–from Scott’s diary–
“Night camp 51. Bar. 20,49. T. -6. Had another struggle this afternooon and only managed to get 12 miles (geo.) The very hard pulling has occurred on two rises. It appears that the loose snow is blown over the rises and rests in heaps on the north-facing slopes. It is these heaps that cause our worst troubles.
“The weather looks a little doubtful., a good deal of cirrus cloud in motion over us, radiating E. and W. The wind shifts from S.E. to S.S.W., rising and falling at intervals; it is annoying to the march qs it retards the sledges, but it must help the surface, I think, and so hope for better things to-morrow.”
