LROC Narrow Angle Camera observation M115475912R shows the hummocky terrain north of the Central Peak of Tsiolkovskiy, well within the crater rim - though not a remnant of the slumping of collapsing crater wall material that resulted in the crater's magnificent terraces, but also outside the region flooded by mare basalt. The hummocks formed as the crater rebounded after the shock of impact dissipated. The image field of view is 940 meters, with an solar illumination incidence angle of 75° [NASA/GSFC/Arizona State University] - Sarah Braden, LROC News System, August 26, 2010.
