  Mars Odyssey - Down the Hill

Mars Odyssey - Down the Hill
Image credit: NASA/JPL/ASU

Uploader comment: Most of the hills in this image have dark streaks marking the sides. These dark marks are thought to be where bright dust has been removed by sliding down the hillside, perhaps started by a rock rolling from the rim that was dislodged by gravity.
