This deposit may represent a time when Mars had abundant liquid water on its surface. Scale bar is 250 kilometres (160 mi) long. Layered sedimentary deposits are widespread on Mars.
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9] Layers can be hardened by the action of groundwater.
