Amundsen and Scott both describe very similar conditions on the plateau. Amundsen describes such an experience:
That day we encountered new surface conditions – big, hard snow waves (sastrugi). These were anything but pleasant to work among, especially when one could not see them… it was impossible to keep on one’s feet. Three or four paces was often the most we managed to do before falling down. The sastrugi were very high, and often abrupt; if one came on them unexpectedly, one required to be more than an acrobat to keep one’s feet.
At times Scott had a similar problem keeping his feet:
On a very slippery surface I came an awful ‘purler’ on my shoulder. It is horribly sore tonight.
