An answer to an earlier question...
Interesting, Nick.
Could these orbital variations have resulted in increased evaportion / desication as well?
Could there be a fractal relationship between these cracks on the plane and the polygons in the outcrop?
Oh, our earlier question, "how far down will the rover have to trench outside the crater before the "white" layer is encountered?" is answered, (at least in one location):

I like to be here when I can/
When I get home, cold and tired/
It's good to warm myself beside the fire..."
(well, it is snowing here...)
