It’s All Downhill
This image from the Lunar Reconnaissance Orbiter shows a close-up of an 80-foot-wide boulder on the central peak of Gassendi Crater, a trail left behind it in the dark lunar soil. There’s even a bit of a pile-up of soil in front of it where it came to rest! Several smaller boulders on either side of it have made their own downhill runs as well.
