Here's the question: Is it accurate to say that moving from the Ronne Ice Shelf to the Ross Ice Shelf -- apparently the only sort of journey that's on record -- is travelling essentially east (from below south America) to west (below New Zealand), with a curve that touches the "south pole"?

Are there any vertical traversals on record -- From Belgran II to Mirny -- for example?
