Terraces or Strata on a Crater Slope
ESP_025370_1290  Science Theme: Sedimentary/Layering Processes
This observation shows an interesting layered rock outcrop in the southeast Hellas Region. One of the scientific goals is to look for bedding features that might give clues to what deposited the material: subaerial, subaqueous or polar-ice-like?

Structural features cut through the layered material and strata at this location. Could these features be faults or dikes? Additional images of this region may help us find out.

This caption is based on the original science rationale.
