Keywords: This is another photo from orbit of the polar Martian dunes, taken in April 2008 near the North Pole of Mars. The white areas are [interpreted to be] melting/vaporizing CO2 snow. According to the NASA photo interpreters, the dark streaks are damp sand (water-wet, so I question the CO2 ice ID. Probably a mix), and the "trees" are optical illusions. And very good ones!
