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.
The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 63.7 centimeters (25.1 inches) per pixel (with 2 x 2 binning); objects on the order of 191 centimeters (75.2 inches) across are resolved.] North is up.
