This is not an isolated case of auras accidentally appearing on photographs. I was sent a photo of the site of an Iron Age village in continental
culled from the Internet, which shows what can best be described as a fog patch
immediately above the village site.
Similarly, my friend Dave was investigating a treasure site and turned
up Google Earth aerial and street view photos of the site, which both showed a
patch of isolated fog. Unfortunately the
site turned out to be a scheduled ancient monument so it cannot be investigated
without government permission.
The moral of this story is to take a close look at any photographs of possible treasure sites you have, or come across and if you spot anything that looks as if it might be an aura, you could soon be digging up a fortune.
