There are grids of row-and-column pits discernable in much of the lower-left quadrant, turned at roughly a forty-five degree angle to the observer.
I'd be tempted to say it was an artifact of the spacecraft's imager or the JPEG algorithm, except that there are patches of gridding turned at slight angles to one another throughout the region; they don't all line up like camera or algorithm artifacting would. It looks like the Kingdom Of The Whack-A-Mole down there!
