Hiding something on A moon

A little scifi musing.

What If there was an alien civilization that hid an artifact on A moon (not THE moon) and expected to come back? Kind of like a pirate burying treasure. Where would they place it? Since they would not want just anybody to be able to find it placing a big obvious marker would be out of the question and it would be well hidden.

If the moon in question over the large scale had a homogenous appearance, i.e. there would be no big terrain features that can act as a marker. So for a featureless moon, there would always be 2 constant points. The north and south poles. If the moon is tidally locked, a third point, might exist, the center of the face facing the planet. But due to librations and parallax, the point may be inexact
