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 PIA14853 from the surface.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
