Just a pretty (and enigmatic) picture today, instead of having a go at pseudoscientists. This is a treatment of a HiRISE frame done by Lori Fenton, who studies these things.note 1 Please read Lori's blog for an explanation -- it's extremely interesting.

 Lori Fenton is a planetary aeolian geomorphologist. A dune guru, in other words.
