In relation to the "Cairn" Stones Ric...as I was glancing at the picture, it makes you think about the overall theology or thought pattern of Amelia, if indeed she had to bury Noonan. What her physical status was like...strong or weak...could she have dug a grave or not. I myself believe that this may be the case...lay rocks around your body, and on top...but at the same time have a viking ritual per say where the grave rocks are heaved with some sort of fuel and set on fire. I myself would see her doing this. She may have been a pilot, but her overall structure was petite and very frail and in the situation she would have been in I dont see her exerting herself of all that energy to bury someone. I would check the composite structure of the rocks to see if there is the remote possibility of any soot formation on these. Anyway, this looks like a possible finding myself!
