Much of Mars is covered by sand and dust but in some places stacks of sedimentary layers are visible. In this image, exquisite layering is revealed emerging from the sand in southern Holden Crater. Sequences like these offer a window into Mars' complicated geologic history.
Holden Crater was once a candidate landing area for the Mars Science Laboratory, and is still an intriguing choice today.
The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 52.2 centimeters [20.6 inches] per pixel [with 2 x 2 binning]; objects on the order of 157 centimeters [61.8 inches] across are resolved.) North is up.
