Seeing Boulders From Orbit

Bouncing Boulders on The Far Side of the Moon

"Southwest of Rowland crater on the Moon's farside, a 15 km diameter unnamed crater exhibits many boulder trails on the crater walls in this Lunar Reconnaissance Orbiter image. The boulders range from 1 m to 15 m across and mark a path downslope to the crater floor from a higher elevation."


Bouncing Boulder on Mars Blocks a Slope Streak

"A boulder track is visible in the center of this Mars Reconnaissance Orbiter subimage. The track formed on the sloping wall of an impact crater when a rock bounced or rolled downhill leaving behind marks on the surface. In the full image, you can see its whole path, starting from a cliff to the east, from which it presumably originated."
