First have a look at this LPOD – lunar photo of the day entry.
Then examine this photo I took of a similar feature… 🙂
I wonder if any analogies can me be drawn between the way my pumpkin pie cooled and the way crater Pitatus cooled after it initially formed. Are there similar dynamics at work here or is it just coincidence? After extensive core sampling of pie (yum!) I am no closer to an answer.
At any rate I thought the name was apt.
