Editor's Note: This anomaly was originally observed by David Percy. It is interesting to see another independent photographer arriving at a similar conclusion. Notice that the shadows of all the small rocks on the left of frame also extend in the same direction, not just those in the right foreground. Clearly the slight rise in the right foreground is not the reason for the direction of the shadow divergence.
