I looked, and really, I do think that if there is something in this picture, I believe it is above the stone. That area did appear to have something of note... like something was preparing to take form there, or was just in the process of fading out... hmmm... this was a tough one. But, I do know that old tombstones have a way of 'making pictures' because of the weathering that takes place. It is almost like looking for faces in the clouds.
