Read a different theory couple months back that frost/condensation was enough to freeze around the rock at night and cause “expansion” in the soil up to about an inch into the soil hence moving the rock (very, very) a little at a time. Still doesn’t explain why one direction is usually observed however..

The condensation under a rock on the flat is influence by the direction the sun rises and the nearness of a land rise such as seen behind the rock in the picture. The condensation reduces the coefficient of friction of the rock on the flats soil and the weight of the rock effects the size of the ‘channel walls’, up to a point sustainable by the formation of cie crystals in the condensation enriched soil. ... The side-walls will be noticeable but never high no matter how large the bolder etching the channel.
