This HiRISE image samples the floor of Kasei Valles, a pair of giant channels north of Valles Marineris.

This image is near the source of the southern of the two channels. It shows a surface covered with large plates that are covered with ridges. This kind of "platy-ridged" surface is found on many of the young plains on Mars and on large lava flows in Iceland. The ridges form as the surface of the lava flow hardens as it cools and is crumpled during flow. The plates form as large pieces of this crust raft apart.
