I've thought a lot about that, but on the moon. When/if we get to mars, and someone drives their rover from one place to another. The wheel tracks in the dirt can, eventually, be erased by the winds of Mars.

On the moon, there is no such refresher. In the year 12022, there will be up to 10,000 years of rover tracks covering the surface of the moon. I just wonder what will become of the Apollo 11 landing site. I can imagine it in a bubble in the middle of some mall on the surface of the moon.

They would eventualy get eroded by solar winds (that's why there are eroded craters that we can date) and the like but it'd take a while!
