The crater Nobokov exhibits a rugged basin ring and degraded crater rim. The inset color image suggests that the basin floor may be of a slightly different composition than the surrounding material. The inset color image is a composite of the MDIS Wide Angle Camera filters with the 1000-nm filter depicted in red, the 750-nm filter depicted in green, and the 430-nm filter depicted in blue. The blueish hue in the color image reveals that Nabokov has a slightly shallower spectral slope than many of the younger volcanic terrains on Mercury.
