HiRISE: Curved ridge and layered materials
Curved ridge and layered materials. Is the curved ridge a remnant of inverted stream channel sediment, crater ejecta, or something else (e.g., tectonic)? Are the layered materials sedimentary rock? Beautiful Mars series.

HiRISE: A layered mound in Juventae Chasma
Many of the chasmata (the plural of “chasma”) in Valles Marineris contain light-toned mounds that are distinct from the darker rocks that define the walls. The light-toned mounds, like this one in Juventae Chasma, generally contain sulfates, which are salts … Continue reading
