The article says that the spiral troughs are due to erosion caused by katabatic winds that are deflected by the Coriolis force.
The problem is that the troughs spiral outward in an anti-Coriolis direction. i.e, They curve westward not eastward as would be expected. I wish I had access to the original paper. This seems to be an error in the article. Can anyone with access to paper elaborate?
