Crater in the Mangala Valles Region

Just south of the 2 km high main mass of the Medusae Fossae Formation, in a region dissected by channels, lies an unnamed crater that may have been filled by mud. A channel spills into this crater on its eastern side and may have delivered the material that now covers the floor of the crater. The subdued ridges may be wrinkle ridges in a preexisting lava flow that are now covered by a layer of sediment. The cracked surface is evidence for the subsequent deposition of mud.
