MESSENGER acquired this view of Mercury's surface with an unnamed crater in the center of the image. The crater displays a telephone-shaped collapse feature on its floor. Such a collapse feature, not seen on the floors of other craters in this image, could reflect past volcanic activity at and just below the surface of this particular crater.
