Nothing unusuaol about the slopes
Same as the main crater. It's a small crater sat on the edge of a big crater. Not unsurprisingly, the small one is collapsing into the big one. This cause steep slopes...
Do you want to be more specific here? Which part of the image do you think is "steep"?
(Think carefully about your answer. We've had a couple of rounds already on this topic. You know what my response will likely be...)
