Deformed Layered Sediments in Western Hellas Planitia
ESP_016563_1385  Science Theme: Sedimentary/Layering Processes
The western margin of Alpheus Colles (the large plateau in Hellas Planitia) is bound by a large depression that is the deepest point in the Hellas basin and also the lowest terrain on Mars.

This region is characterized by highly deformed layered sediment nicknamed “honeycomb” or “taffy pull” terrain. The origin of this unusual layered sediment is unknown, but it may be related to an ancient lake or ocean in Hellas.
