Mars' North Pole

Mars' north polar layered deposits comprise a thick stack of icy layers.

Part of this image from NASA's Mars Reconnaissance Orbiter (MRO) has lingering seasonal frost, which serves to accentuate those layers. An additional rationale for this observation is to document new activity in scarp erosion.
