    Well spotted. This is from the same HiRise image as the one in your "blotches" discussion. It's a weird area indeed.

    Don't take this as fact, but I'd suggest we're looking at some kind of 'polygonal cracking' of the surface. Different types of polygon shapes are seen in many of the images here.
