  I'm thinking that this is one of the terraced areas we've looked at recently and the fans are all on the slopes between terraces,

  I think the area may be relatively flat (no slopes)... see http://talk.planetfour.org/#/boards/BPF0000002/discussions/DPF00008be

  Have a look at this one 4 or 5. Screen widths down. This is from the polar layers and the bands of fans are on the slopes between layers.

  Impressive stuff but are the terraces an optical illusion or scientific fact?

  Sorry kith not to scale was just comparing the shape. Antarctica is much bigger about 5000 km along the horizontal axis
