The orientation of light (horizontal direction and angle of incidence) is very useful and therefore important in viewing sedimentary structures. Structures that are invisible in flat light hitting the surface straight on can be revealed when the light source moves to an oblique angle.
Which Orientation below appears to have original top oriented correctly?
