Angie60 might want this for her collection. I'm with you ElizabethB, no idea !!
I've a feeling that I've read somewhere that frozen regolith can 'crack' into these square/polygon shapes and I'm wondering if that might be the case here. I'm absolutely guessing mind you. It might help explain the 'linear vent' effects we see in ice covered images like this:

Yes, thanks, I've collected this. Very similar to the image I was wondering about recently.

It's Easter therefore it's a hot cross bun. Looks to be an example of the polygonal crack type things but on a bigger scale
