Hi3D: A Terraced Crater
This terraced crater is in a region with lots of ice-related geomorphology. The terrace may indicate thickness of an icy layer.

@jurban That could very well be the remnants of even an older crater that was filled in (sediment?) long before the adjacent crater that is geologically younger.
@HiRISE
The circle next to it looks like a crater that was filled in with a different density liquid. Maybe from deep below? It cooled and shrank to reveal the original perimeter.
