This image was acquired in the very late southern summer at an incidence angle of 83.5 degrees (the sun was just 6.5 degrees above the horizon). Rather than being uniformly bright, the high-standing flat areas are brightest near the margins of pits and darker in interior regions.

This pattern may result from deposition or removal of dust and/or carbon dioxide frost. Bright lines probably marking fractures can be seen over the relatively dark high-standing areas.
