The western-most mound of the discontinuous deposit of Medusae Fossae Formation (MFF) shows a style of erosion different from the typical. The MFF commonly displays a range of yardang features, the boat hull shaped ridges that result from wind erosion. This image shows no obvious yardangs and instead shows pits and troughs that appear to be due to collapse rather than wind erosion.
