The Most Bizarre Picture of Mars Ever Taken – NASA

Looking at this picture of the North Pole of Mars makes you think you are viewing a well groomed ski slope in fading daylight with a sprinkling of trees and normal vegetation, but if NASA is to be believed that is only a deception.  

NASA’s Explanation

This image taken near the north pole of Mars shows dark brown streaks over the pink sand. NASA writes about the image, “When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks — streaks that might appear at first to be trees standing in front of the lighter regions, but cast no shadows.
