Perspective views of the farside Virtanen graben created with topography derived from Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) stereo images. The graben (black arrows) extend along a shallowly sloping narrow rise in heavily cratered highland material. The 3-dimensional views were generated by draping a monochrome NAC mosaic over the topography. The bottom perspective view has no vertical exaggeration while in the top perspective view the vertical exaggeration has been increased by five times to bring out subtle changes in elevation and slope.
