A week ago a lady emailed me: "I was just there with a group inside the circle and saw a sun cross design w-cross within a circle on a stone in the ground ever heard of that? The archaeologist I was with was not impressed -I got a pic though. We left salisbury at 640 am that day last week and got there and a Druid group was just leaving , so I think we were in the stones around 745-830? We had an hour in there . I mention that bc no one , not even me could see it in that stone after a certain time."
This is her picture:
Of course some of you may have noticed the random shape on the Altar Stone which enabled me to identify where the mark was.
