In the dark, the rock at the head of the path is dappled with light and shadow. Put in another way, the light and shadow are distributed unevenly across its surface. You would not be able to predict, on the basis of a general understanding of what happens to an object in a dark environment where that object is illuminated from an angle, exactly which parts of the rock reflect light and which parts are in shadow. This confusing lighting situation is the result of multiple light sources and probably also the presence of one or more objects between these light sources and the rock which cast shadows onto its surface.
