This THEMIS image of rounded hills and ridges in Arcadia Planitia shows a very intriguing geomorphic feature that may be attributed to the presence of an icy-rock mixture of material. Smooth aprons of material are observed to be preferentially located on the cold, north facing slopes of hills and extend further and beyond the deposits located on other sides.
