The south polar residual cap is constantly changing as carbon dioxide sublimates from steep slopes, enlarging pits, and condenses on flat areas, filling pits.

Sometimes the strange landscape produces something that looks familiar, like the mascot of a certain peanut company, who recently died in a commercial, and was "creamated" according to "Saturday Night Live."

At least, he still has Mars.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 49.0 centimeters [19.3 inches] per pixel [with 2 x 2 binning]; objects on the order of 147 centimeters [57.9 inches] across are resolved.) North is up.
