Rolling Rocks inside Shalbatana Vallis (EDM - False Colors; credits: Dr Paolo C. Fienga - Lunexit Team)

In this extra-detail mgnf, the left frame shows boulders moving in two directions, indicating that they had different sources.
The right frame shows a boulder about 4 meters in diameter in the bottom left, having left a track that begins in the upper right. This boulder rolled down the hill, appears to have jumped the crater, bounced a few times, and then rolled to a halt.
