Chaos terrain is typified by regions of blocky, often steep sided, mesas interspersed with deep valleys. With time and erosion the valleys widen and the mesas become smaller. In this region south of Eos Chasma there are regions where the mesas have eroded down into small hills (top of the image), as well as large, steep sided mesas (center to bottom of the image).
