This VIS image shows the part of the crater rim and ejecta surrounding Lonar Crater in the northern plains of Vastitas Borealis. There is a fine scale, radial grooved outer layer of ejecta covered by lobate ejecta nearer the crater rim. The ends of the lobes are taller than the material just inside the end of the lobe. Often called rampart ejecta, this morphology can be caused by impact into a surface that includes volatiles such as sub-surface water or ice.
