This VIS image shows an unnamed crater located in Utopia Planitia. The surface of the ejecta contains radial grooves, visible on both the thicker near crater ejecta and the outer thin ejecta layer. The formation mechanism for the grooves is still unknown but several theories exist including basal surge flows and air pressure rock entrianment.
