The crater in this stunning image has prominent slump deposits that were created as the crater and ejecta collapsed back in on itself immediately after crater formation. If you look closely, you can also see that the rim appears to host small patches of hollows. One clue to understanding hollow formation is that they appear to form preferentially on sunward facing slopes (because this crater is at a high northern latitude, its northern wall gets the most exposure to the Sun). This extra heating may enhance the loss of volatiles from the surface.
