Geologists have a saying - rocks remember.
One of the most important things about the geology on the moon is your descriptions of what you see, comparing them to things that you've seen on Earth so that the geologists and the scientists on the ground would know what you're talking about; and then take pictures of them.
It must have appeared almost as improbable to the earlier geologists, that the laws of earthquakes should one day throw light on the origin of mountains, as it must to the first astronomers, that the fall of an apple should assist in explaining the motions of the moon.
For the stone from the top for geologists, the knowledge of the limits of endurance for the doctors, but above all for the spirit of adventure to keep alive the soul of man.
