Through the haze of a dissipating dust storm in the southern hemisphere, the strange landscape of the eroding Medusa Fossae Formation is evident. In the southern portion of this image, small mounds of sedimentary material are all that remain of a once more continuous layer. This former layer was deposited on a pre-existing landscape that was itself already heavily eroded and disrupted. Yardangs, sand dunes, and an inverted channel are all present in the image.
