The Rosetta spacecraft is orbiting 67P/Churyumov–Gerasimenko, a comet and took this picture. It looks like layering, about 30° sloping down to the right. Could that be right? I learned that comets are “rubble heaps”, so what is this?

I don’t think that is layering, but I don’t know how you explain the structures you seeing my High school Geology did not cover comments.
A lot more sandy than what I would have expected.
As for “rubble heaps” that is the point of Rosetta is because we really did not know much before and the it was all best guess.
Also not all comets might be the same.
