HiPOD (16 October 2018): A Flow-Like Mound within an Equatorial Crater

   – The weird shape of this crater’s interior is likely due to what is called a “periglacial process,” relating to or denoting an area adjacent to a glacier or ice sheet or otherwise subject to repeated freezing and thawing. (263 km above the surface. Black and white is less than 5 km across; enhanced color is less than 1 km.)
