The images appear to show rows of dark "conifers" sprouting from dunes and
hills on the planet surface. But the scene is actually an optical illusion.
The photographs actually show sand dunes coated with a thin layer of frozen
carbon dioxide, or dry ice, less than 240 miles from the planet's north pole
.
