A Light-Toned Deposit in Arsinoes Chaos
The objective of this observation is to examine a light-toned deposit in a region of chaos terrain. The deposit displays a rough surface, in contrast to the smoothness of the surounding area. Some parts of the surface appear as if they were eroded by a fluid flowing north and south. This deposit may have formed in an ancient lake.
