When we acquired this image, it was northern summer and southern winter on Mars, but signs of spring are already starting to appear at latitudes not far from the equator. This image of Penticton Crater, taken at latitude 38 degrees south, shows streamers of seasonal carbon dioxide ice (dry ice) only remaining in places in the terrain that are still partially in the shade.
The turquoise-colored frost (enhanced color)
is protected from the sun in shadowed dips in the ground while the sunlit surface nearby is already frost-free.ID
