APOD 1.2

This picture of the surface of the moon depicts the landing point of the Apollo 17. It shows the lunar module, Challenger, the lunar rover, and the Apollo Lunar Surface Experiments Package (ALSEP). All of these things were left on the moon. The ALSEP was left to monitor the moon's environment and interior. If you look closely you can see tracks left by the lunar rover as well as some faint footprints from Eugene Cernan and Harrison Schmitt, the last men to walk on the moon. The men spent 75 hours on the moon bringing back large amounts of samples. With the manned missions cancelled, it could be quite a while before another man walks on the moon.
