HiPOD (9 November 2018): Pitted Material and Mounds in Chryse Planitia

   – This rough-looking material has many meter-length pits. What exactly is this stuff? Chryse Planitia shows evidence of water erosion in the past, and is the bottom end for many outflow channels from the southern highlands as well as from Valles Marineris and the flanks of the Tharsis bulge. (316 km above the surface. Black and white is less than 5 km across; enhanced color is less than 1 km.)
