This VIS image crosses an unnamed crater in Terra Sabaea. The entire crater floor is covered by materials of unknown origin. Those materials are be eroded and appear to be forming chaos. The channel feature may be related to fluid activity, where the underlying material is losing water and the surface is collapsing – rather than the flow of a river over the surface.
